This was made for MJM3's pen contest. [Arrow keys] move. Get to the blue portal to win. Don't touch red. If your player hits a pink portal, you have a 50% of getting somewhere good or dying. Click your player at the start to change him red or black.
This is a Pen platformer. The boss is possible (though you will die a lot). Catch a B box to make him fall off his mount then touch him till he dies. The green line above his head is a health bar. Thanks to ADIADI11 for the platforming engine.
