(Sorry for the late response). Yes I think we are thinking of the same mechanic. It's a really nice engine and I'll be on the lookout for any new platformers you make!
I was replaying this, and now I realize what you mean't by portals. I'm not sure if it's the same mechanic used for getting from one side of the map to another, but that's the mechanic I was thinking of. (Also, I was at the stream tonight! I'm pleasedontbetakn999).
Thanks for tuning in! I also realized afterwards that you meant the screen-wrap exemplified in World 1-5
I’m playing GameMaker Community games this week and will probably return to level design on Worlds Within Worlds intermittently if I have a gap in the schedule
