Really great game. I managed to get till the end lol.
Love the design here and the various enemy types. It's also cool that the flashlight also sends enemies in the opposite direction.
However, I have some nitpicks. The game is practically begging for a button to fall down platforms. Especially since you can find yourself in positions where you're essentially boxed in by enemies and can't escape. The floating skull is kinda the biggest cause of this, though maybe I just have to get better at the game lol. While I love how the game works and what the process of discovering a painting is, the later levels can be a bit tedious since you have to search for the one cell that you missed.
Regardless though, this is an awesome game. Great job
