Minor checkpoint touch-ups.

Sigh, checkpoints, checkpoints, checkpoints.
Fixed the AI, they didn't work after I changed some parts of the map.

Minor tweaks like box placement and a few tiles.
Made the shortcut in the bottom left corner harder by adding boxes.

I'm 99% sure ALL of the checkpoints are fixed now. Happy racing!

I lied, there were more checkpoints to be fixed.
Moved the starting point to the handle.

New routs caused checkpoint mess-ups. Hopefully those are fixed now.
Also added and item near the lazer.

Replaced the rocket launcher with a lazer.

Tried to "speed up" some of the turns and add more variety to the map.

More checkpoint fixes (I think it's good now) and a few cosmetic changes.

Some checkpoint fixes and some items/boosts are moved around.
