Nice game! I love how you used multiple approaches to the theme in one game, with the level design and the graphics. Very interesting!

The music was fitting, the graphics matched the style of the game, the ghosts turning invisible while not moving was nice (even though I think it would be better if the opposite was true), and the level design amazing!
Forcing the player to think outside the box (yes, literally) made the levels so much more enjoyable!
Great game!

A very fun and very well made glitch game. I like music and the visual style. Overall a very good jam game. Well done.

Really nice take on the theme, the level design was nice once you understand that you have to go out of bounds. On the other side, I would replace seeing only the enemies eyes to seeing a faint shadow when you're not moving. 

Cool game, I thought that the idea of guessing where the invisible walls were by how the walls around them looked was interesting.  I feel like having the enemies go completely invisible might have been more meaningful,  as I could still track them fairly easily from their eyes alone.  I think the game window is also a bit too small (I ended up using alt + enter and played it in fullscreen), and I feel that it may have been better to scale it up a bit.
