Here is a level on which i've been working on for some time; it features a few interesting things, like:
-use-once doors and no-door-thing (nothing exceptional, just used them as they're supposed to be used)
-four mini-game like rooms, or at least that was what i was trying to do :P
-the tail of the main character swings and he goes up and down while he walks (probably the most interesting thing)
-A countdown that makes an invisible wall appear and sorround the end-the-level-thing, thus giving you a time limit (it's in the "kill all the monsters" part)
-the character is also a little slower and jumps a lot less than the robot
I have to admit that I didn't put too much effort in graphics, except for the crocodile animations.
Hope you enjoy the level, have fun!
Edit: ops, I even forgot to put the sword in the level
