This game is cute, and I love speedgames focused on moving quickly and smoothly through levels. However, I don’t have a mouse, so putting spears on the mouse buttons of all things renders this game literally unplayable. There is never a reason to use mouse inputs for things that aren’t positional, so they absolutely do not belong in a platformer like this one. You almost fixed it with your controller support, except that only recall is mapped, not throw. This feels like what you’d get if you asked somebody who has only played FPS games to make a 2D platformer.

Sorry for the inconvenience. I joined the game with a day and a half left so I was mostly scrambling to make it playable, let alone accessible. I use mouse in platformer games myself because it feels more natural, and my own keyboard is very limited on its own (no arrow keys). The controller support was there by default in Unitys input system and I never tested or used it because it wasn't intended
