Thanks for playing - glad you enjoyed it!
The early release on the grapple is a shortcut on my end due to limited time, it prevents a bigger bug if the player leaves the grapple lock-on area due to momentum whilst locked on - totally my fault, but should be simple enough to patch post jam (hopefully lol!)
Parallel bounce - I think I have a solution to this! I'll try and push an update when the voting period ends :)
