So the game feel is really polished and it almost feels like a complete game. It's pretty fun and has a lot of potential, I would suggest adding more power-ups or "game modes", but the concept is solid by itself.
I think the strength difference between a bomb vs a spinned bomb (multiple hits) should be clearer so I would add a number shown in the explosions right when you score! Maybe a threshold to change the explosion color and make them more impactful.
Finally, I would've loved a little more whimsy to make it more "serious", hehe!
Congratulations, great game!
