This game gives me VVVVVV vibes. The self-destruction and chain-reaction mechanic is super satisfying and fun to use. I expected each boss to be be fought in the same way, but after the introduction of blue bullets I liked how I had to strategise more. I couldn't get past the 4th boss though, I kept on healing it so I had to give up. But I think if you tweaked the blue-bullet heal values, the game would be a perfect balance of challenging but fun. Overall, super fun game, one of my favourites from the jam so far.
