I personally found the difficulty to be kinda fine, even at 100%. Btw you beaten me to the screenshot

. I had one at 1% but it is kinda similar ^^
EDIT: Wow there's a tie

That reminds me, I found a bug in Collision Course. If you tie with the opponent in the current version, the Tie! message is off by several bytes. I fixed it in my version, though.
maybe I'm bad at tunnel games lol. I still feel like you move a little too far with one keypress though

Oh and suggestion: maybe have the ai that you are racing have their own sprite so that you can actually 'compete' with him rather than needing to check the dots at the top?
I'll definitely work getting the AI to race with you. I do agree the dots thing is annoying, but the only fix I've made for it so far is instead of dots, it's little 4x4 ships racing across the top of the screen.
I'll take a look at decreasing the key sensitivity as well.
