In what way do you think it's hard? When I patch it, I'd really like to know how it could be better! I've spent a good amount of time playing it myself and had no one to playtest it, so I'm pretty blind to how it feels to try and learn it
It's only my opinion though...I think the gravity scale is low that I cannot predict where would I land on...Like walking on the moon, it is fun but hard to master it. If you think that the gravity is good now, maybe raising the character's speed is a good choice.
