If there weren't those bugs it could be a nice game.
At least the number keys should work everytime they're pressed, the random-pause during the game has to be removed and all magic should go beyond the towers borders (not just most of it).
Wrong collision-detection.
No chain-reactions.
Wrong colours.
-> FAIL!
Repair it and try it again.
Maybe you ask someone who knows how to code.
And pleeeeease upload never again a public pre-alpha.
