Thanks, I appreciate the feedback!
There's a "progress bar" kind of widget on the eraser that shows how much you can still erase, but it's not very clear indeed. I had planned to customise it in order to make it much more obvious, but I just had to ship the game as-is after I got sick. But great feedback nonetheless
You're absolutely right for the jumps as well; there's definitely quite a few improvements to be made in terms of control and how you interact with the environment. I'm new to game dev but I actually learned about Coyote Jump a couple days before the end of the jam; didn't quite get the chance to update it in time sadly!
