This was a pretty fun small arcade-style experience for me! I thought the visuals were nice overall, however the game could have used some anti-aliasing. The music was pretty catchy and the sound design was also very good.
The game was however a bit confusing to me at first, even with the tutorial. I did not really know what to aim for and there was not too much feedback to reinforce correct behavior. After a while the game also became pretty repetitive, as you are essentially doing the same thing over and over, however that is just how arcade-style games work so that is not really on you.
Aside from that it was a fun experience, good job! :)
