This was a cool arcade chaos idea! I liked that the bomb is both the threat and the thing you actually need to use. That made the countdown feel way more active than just a timer ticking down. The boss loop sounds fun too because it keeps you pushing instead of just playing safe.
The controls also give it a more physical feel, which makes the concept stand out more. I like when a game takes a familiar arcade feeling and adds one weird twist. The whole bomb loop sounds stressful in a good way lol. Really neat twist on a boss fight!
