Haha, I should have watched the gifs before playing it. I beat the game, but didn’t use the infinite portals mechanic at the point in the gif, but instead clumsily “portalled” my way first to the room below the 0, then to the spiky room to the left, then up, then to the right to finally get the thing.
I only really learned about that mechanic (i.e. that these things are breakable based on player speed, and not invisible switch triggers or similar) a bit later where infinite portalling was actually required.
Otherwise, great job! The difficulty curve is a bit weird - IMHO the very last room (where you have to Sonic-jump “backwards” via portalling) is way too difficult compared to the ones before, it took me like 15 minutes to finally press the right buttons at the right time there, in many times with a jump I AM VERY SURE I PRESSED simply not registering as I was apparently too close to the edge already.
I definitely love how this shows how even just controlled screenwrapping is a superpower. I mean, technically this game doesn’t do much, this could be a rather simple SMW romhack - however the fact that it’s not allows to see a bit outside the “wrap rectangle”, and is simply more fun to explore the mechanics that way.
