Not badly made, just not too fun.
The game is well made and straight forward, but it's a nice little time waster. It wasn't too original and was quite repetitive, the upgrades didn't increase the fun just the monotony, the game is way too easy and you don't feel accomplished no matter how well you do, there is very little skill involved, i might as well be holding up the whole time for the amount of necessary movement. The game would be better if it had a bit more variation and, on a personal note, a different soundtrack.
