Nice little game that gives me some overcooked vibes! First of all, you really need an angry voice for a boss. I can just imagine him getting angry at your mistakes. Also, maybe adding tool switching on a mouse wheel would be nice. Also, consider adding different challenges - maybe some wouldn't need an immediate reaction and won't increase the red line, but can blow up later, maybe others can start a chain reaction... Also, I think the game gets a bit unbalanced in the end, I can't manage to fix all the leaks. Anyway, amazing job for a first game jam!
