Nice idea, essentially Tetris plus quick calculations. I was just struggling a bit with the game-play:
- It would be much better to move the tiles like in Tetris and not to chose where the next one will fall down. If you think about it: why do they fall down if there destination is already predetermined?
- The controls are too fast: I could rarely get the blocks where I wanted them to be.
- The game starts too fast for beginners.
- The help text shouldn't be displayed in these super huge bold upper case letters.
- Bombs could be automatic or actually just play without them, like in Tetris.
- When you play on the webpage and press Quit, you get to a menue where you can choose Quit, and then Exit.....
Overall a cute idea that can be made into a nice game!
