Awesome! That's a pretty good amount of progress so thanks so much for playing! And hopefully you have some better luck next attempt. I really appreciate your feedback. That is a really good point about the difficult sections having alternate ways to return to the hub just in case you want to come back and try later without backtracking through the entire level, and it is certainly something I'll take to heart going forward. As far as the difficulty spikes go, some are intentional and some are steeper than I intended, I think I often worry about things being seen as too simple while designing levels and end up overcorrecting in the wrong direction.
I also agree on the easing bit, it does just start you off needing to make a difficult precise jump followed by a well timed one, there's not really a simple one to start out and let the player get comfortable with that mechanic. I am glad you had fun with what combat there managed to be in the finished game, we had much bigger plans for melee enemies, ranged enemies, drones, boss fights, etc and ended up with just the turret due to time restraints, but if we continue working on it we will certainly add those missing features in. I think if we do continue working on it there will be some big overhauls with the level design, puzzle design, conveyance, player movement, and just more content!
