Oh I totally missed that there was an in-game way to set the sensitivity, that's on me then. The movement did remind me a lot of ultrakill in like the best of ways, definitely a big highlight!
No worries, it honestly is probably not very clear that you can; so I've added it to the game's description! Also, I lost a looot of development time to taking breaks to play ULTRAKILL for inspiration so, that definitely seeped in a bit LOL
