Hi Enji, Happy to hear you enjoyed the general mood/art direction of the game and that you enjoyed playing it.
Increasing the hitbox sizes of enemies is a good idea. It can be very hard to hit enemies when you are both moving.
On the point about controls (not using mouse to control ship direction), I would actually disagree. I have found in testing that the ship is very clunky to move when not using the mouse, and it is almost impossible to aim or control the ships rotation with any degree of precision.
Finally, I'm glad you appreciate the detailed feedback I leave. I hope you found it useful. Thank you for your in depth suggestions too 🙂.
