Thanks so much for the feedback!
I'm not sure if you mean you used W/S to move the camera beyond the drawing. I didn't have time to code a scroll lock, but I tried to add enough artwork to cover immediate edge cases (or people could soar forever if they really wanted to lol). But if something else happened that moved the camera or gameplay out of bounds, I'd be curious to know more about that bug so I could try to replicate it.
Either way, I'll definitely keep all of the feedback and advice in mind for my next game. Thanks again so much for playing!
