I really like the math/word combos. There was an issue on wave 6 where the word was "worked" (no caps) but my ship wouldn't fire. I like the user-submitted words/phrases idea. 4/5, could easily be 5/5 with some additional features and fine tuning.
So I really like the concept. But I feel like I'm just moving all the blocks of every match to the bottom of the column(s). I might suggest taking out the "clear all blocks above a match" part and increasing some other difficulty aspect. 4/5
What is needed is a SHORT delay timer on a piece you just moved. You should be keeping up with at least 3 pieces, not just rocketing your queen around.
For a first game... not terrible. But there's something weird about the way the ship shoots. The bullets move towards the center, not in a straight line. Makes it hard to shoot. And the click-fire delay doesn't help.
