Hey! Thanks for the feedback!
We tried going with a minimalist approach to explanation and texts, hoping the game would be easy to understand but I think we might have messed up and maybe a little "how to" would have served the game well.
FYI:
Hold mouse button to start shooting
When you're on a bed you can hold spacebar to make your character sleep and make the lightzone grow!
If your bullets escape from the light, your lightzone will shrink! You need to be precise with your shots.
