I like gameplay in the game, but it's a little frustraiting when the ammo is empty and there is nothing you can do to fill them (maybe I missed something). On my second try the skill panel has broken and didn't apper as well. Some times got lost in the same coridors that moves in different directions.
But overall it's a quite a full game with interesting story and cute cube design. I liked narration part except of cases when you stack in a dialog and enemies is finishing you, haha. And I liked how you are using the sound to indicate gameplay moments. Good job!
