Not sure why people are being so critical of this game.
I can clearly tell what everthing is, the game works the way its supposed to, and it has an end.
That is why I gave it 3 starts; there is room for improvement:
*It would make sense to have the move forward key be right arrow, and install a left arrow key to slow down or go in reverse
* The tennis ball is probably what is killing people - I know I could never pass it normally. I had to discover the space key and time it at the 2nd hill.
There are alot of games like this, but just because its been done doesn't mean you shouldn't try to make your own version of it - especially if you can come up with a new spin on it (idk how many FNAF games there are now). Keep working, you are on the right track!
