Interesting gameplay! I wonder what inspiration you had for this game. I see other comments and I agree with a lot of them. Here's my piece: just turning on the damage would make sense, all those projectiles didn't deal any damage - thus not pushing me to be more careful with the projectiles and not using the rewind tool. And free to safely explore, and in turn, discovering that I can walk over walls and props. In regards to game design for projectiles, I see your nod to bullet hell! Otherwise, cool game!
