Hello, everyone! I'm back with another Quick 'N' Dirty cart!
This time, I've put together a little planet generation and rendering system I'm looking to use in a bigger project. From the cart's intro comments:
This is a very very work-in progress planet generator. I'm not (yet) going for huge amounts of complexity or variation in my texture generator. Rather, right now, I'm working to make as *performant* a planet generator and renderer as I reasonably can. To generate terrain, I'm using the diamond-square algorithm to rende a 64x128 pixel heightmap on the bottom half of the sprite sheet, which is mapped to the bottom half of the PICO-8 map. To help ensure that we're not impacting performance, I've added some break logic to the rendering routine that lets us stop processing once we hit a certain CPU threshold, spreading the work across a few frames. This is fast enough that planets render in well under a second, even with the added overhead of the break logic. Of note here is that planet generation is entirely deterministic and stems from a single seed value. If you want to build a galaxy of planets, all you need to do is store a number per planet and re-render them on the fly. To render, I'm relying on tline to draw a linearly-banded UV map that reads from the bottom half of PICO-8's map and draws a series of horizontal tlines across the unit circle. At higher rotation rates, this is very obviously not an accurate way to draw a sphere, but it *is* a blazingly *fast* way to do it, and at slow enough rotation rates, it's good enough to fool the casual observer. Rendering times increase as the planet grows, but even when the planet takes up most of the screen it only eats about 30% of the standard update cycle's CPU time. Future improvements will be focused on adding some good variety to the planets being generated, along with features like polar regions and wind/precipitation-based biome coloring. |
Arrow keys to zoom and control the speed of rotation; O/Z to generate a new planet.
Have fun!

Caverns of Dark Adventure is a traditional roguelike for PICO-8. You've become lost in an unknown cave system while collecting luma crystals for your village elder. Gather more luma crystals to light your way and escape the dangerous caverns!
Use the directional buttons to move. To ascend a passage or pick up an item, press X. To attack a creature or harvest luma crystals, move in their direction. To wait a turn, press X. To wait until fully healed, hold O and press X. To view your inventory, hold O and press up. On the inventory screen: To select an item, press up/down. To equip, unequip, or use an item, press X. To drop an item (if unequipped), press right. To return to the main screen, press O. For more information see the manual:

Make perfect snowflakes and listen to lovely holiday music
Created for the 2024 PICO-8 Advent Calendar
Thanks to @bikibird for organizing the Calendar and providing feedback
P.S. If you'd like to use any of the music from this cart, let me know and I can post the songs separately -- songs 2 and 3 are buried in spritesheet/map data so a bit hard to get at.

A Blob Journey
Is a puzzle platformer with a pinch of Sokoban
Help Blu to accomplish his initiatory journey throught the Volcano, you'll need thinking and reflexes !
- 30 levels
- just one button to do all the actions
- portals, switchs, doors ...
- a lot of gems to collect
- find secret passages
- compare your highscores with other players
- speedrun.com challenge (soon)
- the first 17 levels are like a progressive tutorial, the following are more challenging !
More levels to come, stay tuned...
Your comments are very welcomed, game ballance, game mechanics, gfx, sound, music... 🙏

Can Someone please tell me if its even possible to get the spritesheet into a png image.
doesn't have to be png can be any format that can be somehow formated to a png.
I cant even find the gfx file on my file Explorer (not the picotron one, the real one).
The only way I know, would be to make a screenshot of the map where all the tiles are, but is this really the only way?.
thanks in advance

Hi everyone,
I would like to call functions within a table from within a for loop. The type of loop I want to use is as follows;
for x=#enemy,1,-1 do enemy.restoreenemybg[x]() end |
No matter what combination I try, I just can't get it to work.
FYI - The reason I'm using this type of for loop is because I need to loop in reverse. The following version doesn't allow this.
for e in all(enemy) |
I would really appreciate any help on this.
Many thanks,

Old Man Winter and Santa Claus have been feuding all year. It started with yard signs and then things escalated. Now OMW is blowing up a big storm on Christmas Eve!
You, Jack Frost, must blow away the snow so that Santa can get out and make his deliveries.
Controls
Controls are simple. Just use 🅾️ (Z key on computer keyboard) to blow a puff air. This propels jack backward and changes the air currents to redirect the snow, hopefully away from Santa's house.

a gentle snowfall. might make a good background or screensaver, or just run it if you want some winter wonderland this holiday season!

Eyebone has always been protective of the holidays, but a citywide blackout on Christmas Eve sends her over the edge.
TUTORIAL:
O/Z to shoot Eyebone's iconic candy canes
X to shoot Eyebone's Legendary Meter Attack
METER:
Increases every time an enemy is hit. Can be fired when halfway full. When completely full, the shot is larger and makes Eyebone invincible for a few seconds.
SCORE MULTIPLIERS
Having Reindeer- +1
Going over ten seconds without being hit- +2
Having 1 heart left- +5
Made for 2024 Pico 8 Advent Calendar.

A mod of celeste where you climb instead of dash.
Actually, it pretty much changes everything about the fundamental movement of the game entirely. Don't worry, the entire thing is very polished, and even tries to mimic the feel of the original maps.
Strongly inspired by the climbing in the modern Celeste.
PLEASE READ THE INFO BELOW THE CART AS IT IS CRUTIAL FOR UNDERSTANDING SOME FUNDIMENTAL CHANGES MADE TO THE GAME TO ALLOW IT TO HAVE NO DASH, AS WELL AS INFORMATION ON STAMINA AND CLIMBING.
Maybe I should call it CLIMBLESTE
v0.4 (8 berries):
Keys - Move
Z/C - Jump
X/V - Climb (When on wall)
Up - Grip (Holds on wall)
Down - Slide (Makes you rapidly go down wall, restores some stamina.)
Z/C - Wall Jump (When on wall)
Controls:
This mod reworks flying berries due to the lack of a dash. They now fly away if you take more than 10 seconds per level. This encourages you to speedrun the game to get all of the berries.
You are unable to slide or climb on ice.
Angel chest are the white chest (aren't fully implemented, don't appear in game) that have a flying berry inside.
You need Stamina to climb or jump around. The less stamina you have the less speed is reduced by wall slides.
Grey balloons can be bounced on, takes a small amount of stamina.
Things that reduce stamina:
-Wall jumping
-Climbing
-Griping
-Wall slides
-Jumping without full stamina (jumping with full stamina has no changes)
-Grey balloons
Things that increase stamina:
-Being on the ground
-Sliding with Down key
-Balloons
Stamina is represented by both hair color and the wheel next to you.
Red - Near full
Pink - Slightly depleted
Dark Pink - Half left
Light Grey - Less than half left
Blue - Very little left
Dark blue - Almost empty
Dark Grey - Empty
Note: Making the stamina wheel super smooth like that took like three hours. Had to learn pallet cycling.

Not sure if this is in the pipeline but the tabs in the code editor are very small and you cant see the entirety of the filename. Might be good to have a tooltip if you hover over the tab so you know the name of the tab your working in.

Assemble the three parts of the ship and fill it with six fuel packs.
You can go through the margins of the screen and you will appear on the opposite side.
When you load with a ship piece or fuel pack you can drop it passing over the base piece of the ship.
Once the ship is assembled and full fueled, get into the base piece to leave the planet.
Features:
· Six types of enemies
· Four powerups
· Random platform level generation
· Hiscore saving
· Credits to continue game (lossing the score)
Good luck!
Inspired by Ultimate's classic ZX Spectrum game.
