Playing this game, I could feel what the intentions were, collect the potions so you can turn into stronger variants of yourself, and then it's an infinite slaughter of your creation. However, with the randomly generated structures of the level, the difference in altitude make this game not that fun to navigate, because one slip near the beginning makes you fall 250 ft. to the ground. I was also only able to find one changing potion, so maybe I was just bad and didn't quite look everywhere, but the potion placements are random as well. The jumping is strange near the beginning when you are the mimic's original form, it feels sluggish until you transform, so that was just confusing. Last thing, the attack animation and speed is far too slow to be used for actual combat, considering the speed of which an enemy can attack you instead.
The game has potential, but the geometry has to be more forgiving, the attack needs to be faster and effective, and music would be nice too. Maybe a shift to rebuilt levels instead of random generation?
Anyhow, good attempt, and I hope you keep creating!
