I think there is some fun potential, the game loop is naturally enjoyable and thats the most important part! Some feedback:
- Sometimes the game lags when the particle effects start.
- I was able to get out of the viewport and it was impossible to get back on the screen (this happened twice on the bottom of the screen, maybe a res issue?)
- I agree with the others that it starts off a bit slow / boring, then during the middle of the game it is really enjoyable and then suddenly gets really hard.
I do like the movement mechanic though, it separates it from them sea of games that do basically the same.
