Fixed some bugs

I fixed a bunch of bugs that I couldn't deal with in time for the QRMJam. I hope the minigame game is now more or less playable. Here are the changes I made to it after the jam:

• Fixed some cases of the AI jumping too early and missing platforms.
• The CPU character will respawn if left too far behind.
• The CPU character will respawn if you have to wait for it too long at the goal.
• Jumping repeatedly is now possible by holding down the jump key.
• Made the lowercase f look less like p.
• Reduced the download and install sizes a bit.
• Added eye blinking animations for the large sprites.
