Good game, but it needs a lot of improvement
I liked it, but there are several areas you could make better.
1) Some background music would help.
2) Something needs to be done about the white edge to the playing field.
3) Some kind of time limit would make the game more exciting.
4) Nothing happened when I reached the end, you need to let the player know they've reached the goal.
5) More levels.
You've got the beginnings of a good game; you just need to expand on it.
