Hey, thanks for the great and thorough suggestions! Definitely agreed on the reset button - I planned to build that out for the jam, but I ended up running out of time. In hindsight, I should've started by implementing the bare-bones reset functionality for the jam (no animations, etc), just tied to a keyboard hotkey or something. Will keep in mind for future jams. :)
Also agreed on the camera issues - I think I'll be increasing FOV and decreasing the follow lag. Regarding the section in level 4 where you have to drop down, there is actually a way to "tether" down (by holding left-mouse down and tapping right-mouse) in a more controlled fashion, instead of just falling and hoping to be able to push off the anchor fast enough. To some extent, I made that part of the level in order to teach that skill, but I agree that it wasn't very intuitive or natural, and that a better camera would've allowed flexibility in how players approach the level.
Thanks again for the kind words and great feedback - I really appreciate it.
