Cool game! The faces on the main menu character are a nice touch and I love that selecting the difficulty is not just a button! The chromatic aberration on everything works great and gives a nice arcade-y vibe. Great job!
Some hopefully helpful criticism:
- Spam clicking as a bossfight is just not fun in my opinion.
- Screen wrapping is generally a great mechanic and has the potential to make combat a lot more interesting. However, by just standing at the edge and shooting until the enemies almost reach you, and then wrapping to the other side makes every encounter trivial, which also defeats the risk mechanic. Enemies really need to use screen wrapping to track you as well.
