Thank you very much! I worked the most on the terrain, optimisation and character movement so I think that explains it!
At first the controls where supposed to be a lot more complicated, using controllers, but I gave up on it as some people might only have a keyboard in the jam. And from that I merged jumping and dashing in one key, removed the stop sliding key, as you can just press back to brake, and made the attacks target the train as soon as you are close enough.
