Thank you for the feedback! In regards to the rock, I'll be honest and say I procrastinated and while I did have a good chunk of time left to try and fix it at the end, I decided not to risk messing up something crucial and left it in as stable a state I could get it into.
I'm glad you liked the controls! I spent some time tweaking values there to try and make it as enjoyable as possible.
Thanks for playing!
