First off, I really enjoyed it, well done!
> I can get up to around 110wpm without errors in a general typing test, but because of this constant mistargeting, I was capped around 60wpm with 90% accuracy.
Same here, most other tools measure me at ~130wpm (if I'm nicely warmed up) but I couldn't get above ~65wpm/93% accuracy on the game.
I'd agree with the other comments about a faster progression through the game. I'd like it to quickly move forward to roughly the level I want to be on. Shunt me forward a lot, if I die then shut me back half way from where I was (e.g., 1 > 20 > 40 (died) > 30 > 35 (died) > 33 > 34, etc).
In my ideal 'expert mode' I'd want to be playing so that it quickly finds a level that I can complete a certain percentage of the time but allows me to die a few times on a level before assuming that one was too much for me; some times you get caught out by something random that causes you to fail to complete on a level you'd normally have no trouble on.
