While the gameplay is very simple, just popping balloons, the movement and graphical effects are very satisfying. I like the chromatic aberration as you reach top speed and the how the walls stretch when you bounce off of them. Even ramming the orbs feels good. Presentation wise, this game is excellent.
When you reach enough stages, the game has a severe performance drop and becomes slow motion. It is actually kind of satisfying to "unlock" the frame rate again by destroying more orbs. However it eventually becomes unplayable.
Apparently the enemies can damage you? I didn't notice that while playing. If there were intelligent enemies and more than just shooting and ramming, this would make a great full-sized game.
