I don't plan on actually submitting my project (and won't have it finished by September; I took a good while to actually get properly going again after July mostly went to Art Fight) but I'm making a multiplayer top-down shooter with optional mouse controls and a toy theme, where you control a remote controlled hovercraft toy that drifts around and can be boosted towards different directions.
You could compare it to tanks (like the tank minigame in Wii Play) except the thing you're controlling is continuously moving forwards and bounces off of walls. There's a separate movement direction and shooting direction, where one button shoots in the shooting direction, and the other changes the moving direction to the shooting direction. With a SNES mouse, the shooting direction always looks towards a cursor. With a standard controller, pressing a button on the d-pad will make the shooting direction start rotating to reach the target direction you pressed.
It's a sequel to https://novasquirrel.itch.io/sliding-blaster but greatly expanded.
