It's been a long road of constant tweaking to try and get the game to feel right to control, so I'm happy to see that you feel that I'm on the right track, even if it's not quite there yet
Are you running the Windows version at a high framerate? I noticed jumps being skipped when running at 120fps on Linux, but it should be locked to 60. Maybe the Windows version isn't 60fps locked, but it works fine on my machine
