I liked your writing, and the music was fun. The effects were great, but they were too bright, and I couldn’t see anything on the lower part of the screen. The long jump from rockets doesn’t work very well either. It only works when I’m near a rocket, not while I’m in its path.
The scoring also needs some polish, since I could stay in the level for a long time without losing but also without gaining any score. I mostly just collected the time objects and kept extending the timer.
