Thank you for trying it out!
You have a fair point on the jumping.
Originally, he jumped the same height all the time. However, it felt weird that he could propel himself 2 meters into the air while leaning all the way over, so we instead made the height of the jump take his angle into account. To make it not feel like a straight nerf, we also made his jump propel him forward if done at an angle.
Did this work? Kinda...
The jump feels a little lackluster at times because it seems like you get zero height even if you're not leaning all the way over - this is partially the fault of the hastily-implemented custom physics.
We're working on ways to improve the physics in general, so this is valuable feedback. Thank you!
