well made :D but i got an idea on how to make it simpler: use "map()" (draw the map) and "mset(x,y,spr)" (set a tile on the map) so you dont have to use a table ;)

@RealShadowCaster
All of these ideas sound great but i wouldnt be able to implement it, i am very beginner.

@TehBeeKnee, do you have previous experience with other programming languages ? I could help you with the pico-8 and lua specifics.

@RealShadowCaster I know the basics of python, some javascript and a little c#. But im planning to learn lua.
