Awesome game so far in terms of graphics and core combat mechanics-- chaining together teleports to fight the ranged enemies while cutting swaths through the small enemies is pretty fun. The level graphics are super pretty, and the M.C. Escher-like juxtaposition between the always-flat world and apparent depth and elevation changes is much more fun than frustrating or confusing.
Unfortunately, the game is currently extremely short and furthermore, really needs character interactions (and preferably imho at least a plot) to back up the environmental storytelling. I see you are working on adding a boss fight after what's currently the last room, and that will definitely be cool and more of those are of course an important addition to this sort of game, but I hope that the world will be more fleshed out and populated in the future as well.
