Like the concept, a lot. Maybe would be nice with levels, starting out easy and getting progressively harder, so you could learn to master the controls as you go.
Good game, and I disagree about the coloring - I love the wooden platforms and have no trouble with a yellow ball and yellow stars. Maybe nunespt needs to adjust the color on his monitor? Would be great if you added levels, and maybe made the first level easy and then they could progress in difficulty.
Lots of bugs. Twice I landed on my feet and the round wouldn't end. Also, if you complete the goal, you get taken to the next level without a chance to shop, with no additional money earned, and you lose items.
As someone else said, if you have trouble, just work on getting the top half right, don't worry about the bottom at all. Then when you get the top half done, cover it and work on the bottom. Much easier. Love Bart's games!
