Tic-Tac-Go

I like the concept, if you could punch up the environment a bit with some music, better sounds, extra combos etc I think it would be pretty fun!

Things I'd like would be if the difficulty increased a bit faster, if you could touch a column to change your symbol if your symbol is in it (using mouse input, at least, makes it kind of annoying to have to reposition when I'm looking at what's coming), maybe having the selected column highlighted to some degree - but most of all, change the hit boxes on the oncoming symbols? So that if I move columns after a set has passed, I feel it would be less frustrating when I clip the back end of one, seeing as I have no control over the speed of movement (and after moving only one column a few times, moving over to the other side gives the piece a much higher speed) and I end up clipping the top of the symbol in the column next to me.

Maybe instead of collisions ending the game, they merely deplete your score and ruin a combo (if you put that in)? That was you have more of an endless runner and something less likely to be put down when a round is over.
