It was the second of these two rooms, I had grabbed screenshots of both, just in case the door itself was the problem:
(Unfortunately, I hadn't grabbed a screenshot of the visual garbage.)

Alright, I'll focus on those rooms and see if I can find something. Thanks.
In the next build, I have taken take of the problem of your jump halting as you attack. I relocated where the jump is checked for move + attack and it seems to be working. You cannot do is jump backwards while you attack, but you can go forward without any problems.
Update 1: Yeah, I see some weird glitch happening when you jump. I need to see what is causing this and what I can do to fix it. I think this is something that is affecting all rooms
Update 2: Okay, so it looks like there may have been a problem with a value being treated as a whole number when it was a fraction and that caused a glitch when drawing the screen after warping to the next room. After playing with the value, I can go back and forth between rooms without any problems. Nice find!
