The art in this game is really lovely! I really liked the idea as well, but the execution ended up being kind of frustrating for me - I could never get past level 2. I suspect part of it is just that I'm not terribly good at this sort of game, but I was absolutely terrible at lining up the laser properly, and also could never quite place the bomb in the correct spot. I really wish there was some telegraphing of when your moves from the previous loop are about to go, though, since I was basically always dodging the enemies or something such that my laser/bomb placement from the last time ended up being useless, and then with the wasted moves, I no longer have enough damage to clear the levels. The bullets from the previous timeline also ended up basically always being useless, so the lock to only 4 shots felt especially brutal.
I will fully admit that a lot of these issues are likely because I'm not great at this genre of game to begin with, and probably could be more strategic about how I play. It's a really interesting concept that I hope you keep playing with after the jam, and I really, really liked the art direction you chose and how it was a tribute to a specific artist!
