Besides the sprite flickering and being able to move outside of the level bounds, sometimes when pressing x and the console is revealed the game won't register it, so you have to move away and come back and press x again so the game registers it. Also sometimes I'll reveal a tile next to the console and the game will register it as being revealed.
Besides those small issues the game is really cute and fun in its own unique way. Loved playing it, good job! :)
