Lovely build, seems pretty much ready to polish
I quite enjoyed the multiplayer where you have to predict the direction of your bullet like a flying game, I heard from you that the single-player was not the main focus so I will just say that in single-player everything is flat because all the enemies can only charge you in one direction without so they are basically a target practice that sometimes shoots you back, more interesting are the bosses but they probably need some balancing and a lot of playtesting.
What I would like to see is:
- Decrease falling speed
- Bullet readability in any type of background
- Controller friendly options
I don't know what is your direction from here, it's a bizarre combination from a gameplay perspective I feel there could exist a user base for this game full of shitposter, a full package could be a short single-player, an active player base on discord and a level editor.
