A lot of people seem to just be spamming this, so I'll actually try to say the right things:
1. Why don't the cars stay on the track? It's nearly impossible not to make the back car flip over.
2. There needs to be some sort of straight-edge tool to go with the pencil. It's too hard to draw straight-lines the whole way, which makes the cars flip more.
3. I know you want people to feel challenged to get all the coins, but sometimes there are too many odds and too early in the game. Maybe even out the challenges and make it more worth while to work up to the harder ones.
It's a good concept, but it could be a lot better.
What in the game defines a "Perfect Track?"
Why is it the track cannot go down, or the cars fly off?
How am I supposed to even get enough coins to finish if this is the case?
What are you going to do, if anything, to fix these problems?!?
I found it very difficult to get a perfect on most of the tracks, even the ones in the beginning. . .
You, unfortunately, get my lowest rating thus far. . .
