Amazing concept, I always love a good mini-game's game! I do believe I had the same issue as lootss (text not lining up), seems to be related to restarting the game? I've did an F5 and everything went back to normal.
If can share a feedback, I do think the difficulty is a little bit harder than it should be (when I was trying to learn I've received a game over pretty quick). But that's very easy to tweak. Anyway, amazing job!
