This is fun, I played it a few times without paying attention to the score and trying to clear it as many times as possible, kind of like a wordless, frantic typing game.
Playing it trying to get a high score resulted in a slower, more strategic gameplay - more focused on dodging and waiting, saving clears and dashes as much as possible.
I feel like the game could be improved a bit by making the letter distribution a bit less random (maybe instead of positioning randomly the letters one by one, positioning by group of 3 to 5 in predetermined patterns?), and less frequent in the top-right corner where the enemies spawn.
But it was still overall a fun time!
