Fun concept, I lold at the error throwers and got all the way to max level. I feel like you didn't have time to fully complete the game, so I hope the rest of my comment will help you with prioritizing what to do next. These are the most key things I felt were missing when I played:
- The enemies' reaction to being hit is very subtle. Later in the game, I have no idea what I've hit.
- After I got to max level, I couldn't gain extra score playing further.
- I wasn't sure what the luck stat did until my second playthrough when I noticed I was dodging some shots.
- At max speed I was as fast as my bullets. Maybe this was intended, but just felt a little strange.
