Oh, I want more :) ...
... because it was pretty fun. The surreal presentation is great and fits the theme perfectly, I love the font used in the dialogs, the mind bars and that each room presents a different environment. The music is great and the sound effects fit (I think there's missing one when you hit an enemy?). The game also controls perfectly. I even died once (or twice) so the difficulty is perfect too, the few available sequences were fun.
I'm torn about one thing : I absolutely love the look of the character including the shrinking animation, yet everything else look great too and fits super well together while the character arguably fits a tiny bit worse with its clean look compared with the super detailed look of the other things.
Thanks for sharing!
