You guys have made wonderful games, and I wish, if you could, make this my favorite game ever. What I would like would be a level editor. This reminds me way back when I would make a race track with every single thing in my room I needed. The wooden blocks, the dice, even the hardwood flooring. You could also add upgrades, you could add more cars for the demo (a real problem). Those are two things I have listed. Two things. If you don't want to listen to me, listen to your biggest fans.
