I like your dedication to the arcade style with just 5 colors and 5 instruments, really helped to tie the entire game together. I kept replaying trying to discover that one perfect strategy and always had a good laugh when it inevitably backfired and I'd launch off the map into lava. This game was a lot of fun and I really enjoyed it.
The only suggestion I have is to make some of the menu elements bigger, it all felt kinda small for some reason.
I think this game could work perfectly in a multiplayer game with each player trying to survive as long as possible while bombs explode everywhere.
Overall fun game and thanks for the laughs!
