I will definitely explore using the mouse for controls! That's a great idea as it solves my simultaneous keypress issue, and I feel kind of ridiculous being so nearsighted about it. It sounds like it's even already working, so I will give it a try and at least update the description to reflect it for now. And I have done that same trick inside the walls for the last jump many times during testing, myself. Nicely done figuring it out!
Time constraints were the main reason I didn't change it at first, but I ended up kind of liking the rule-breaking exploration element of getting into the walls and seeing what you could do, so I think that might stick around at least in some form.
Also very happy to finally have the eggs brought up. Gold star!
