Very cool! The chain reactions were fun and satisfying, and it was fun to look at a whole level and try to predict which box I would need to hit to get the whole chain. I'd love to play more levels of this if you add more :)
I think my only negative feedback is that the SFX could be improved. I think a lot of the satisfaction of this game comes from watching and hearing the chain reaction go off just right, and the sound effects are a little samey. Some pitch randomization would probably help, or maybe each successive chained shot could rise in pitch?
Overall great jam game ^u^
