Nice game, I like the idea a lot. I feel with some changes it could work a lot better, but I'm not smart enough to know what those could be hehe. I have a few suggestions though:
- The controls need to be tighter: not sure how to fix it but right now its too hard to move accurately. It may be the speed, the arrow movement may not be "jumpy" enough (jump each square), maybe it's just to many columns.
- This may help with the previous issue: the feedback on when the next block is coming isn't great. Maybe you could use the music, since its a constant beat, perhaps an animation of the arrow getting filled or something.
- 0 block could be fun, so you can kill 2pieces that already add to the value.
- When you add to the correct value at the same vertically and horizonally only one of them explodes, (I think its vertical?), I think it would be more fun if both of them did.
- The UI could use a lot of work. I'm not good at UI design, so I may be wrong, I think it needs more feedback for the player everywhere
- I don't like the bomb mechanic as it is implemented right now, I don't know how I would changes but right now I don't think it's fun or adds anything interesting to the gameplay.
Thank you for making this awesome game, very enjoyable! Keep working on it, I'd love to play it again as it evolves.
