Thank you for playing our game!
The grappling hook definitely takes time to get used to since your momentum and speed is based on where you attach and your movement input during the swing. There are a few bugs with the targeting of the grappling hook that we were not able to fix before submission, sorry about that!
Regarding the controls, they were designed to have one hand on WASD, shift, and space, with the other hand being on J and K or Left Click and Right Click. I would love to hear your suggestion on how to improve the control layout since we had trouble deciding on it.
I am glad you enjoyed our game, thanks a lot for the good feedback!
