I enjoyed playing this game. It is a pretty simple concept but working fine, not that innovative in my opinion. Art is simple but effective, everything is consistent (which is great). The audio is pleasant and clean, a good point.
I have my doubts about the way you handled the theme of the jam, because actually the game isn't a liar. The thing is that you have to kill enemies to prove there are enemies so you can go to the next room.
Also, the texts at the begining are very long, I would like something more quick or directly anchored in the gameplay.
Overall the game is fun, I had fun times testing it. Well done.
