Thank you for playing, and for the extensive feedback.
I actually though sprinting midair would do something, but I checked and you're right, it doesn't. If I ever continue working on this, I would have worked on the Movement anyway as there are still lots of stuff I wish I had in it (Sliding, Wallrunning/Jumping, better Grappling).
A tutorial-Map is also something I've thought about during the jam, but I really didn't have the time for it.
Best Score I've heard from was 1300 in one of the comments, but I didn't know which difficulty that was.
An actual Leaderboard (with scores sorted per Map) would definitely nice for the actual game.
Glad you enjoyed playing.
