Good gameplay
and good design as well. Very good design, it reminded me of those old orisinal games if you're familiar with them. While there's an obvious lack of originality (Ball revamped immediately comes to mind,) the different graphical style and star-collecting feature are enough to set it apart.
After playing for a while I ended up enjoying it, but the controls definitely didn't seem right for the first few levels (velocity and gravity were too high). Soon I adjusted and the game flowed really well. All in all, it was very enjoyable, and I hope to see some more.
