Great work on the game, by the way!
Honestly one of the best free-to-play games I've played

I've tried, but I haven't managed to get past it .-.

Thanks for the info though, I'll keep trying. I'll also edit the screenshot caption, since I haven't actually softlocked the game.

You should have the wall jump by the time you get here. As long as you have that, you have everything you need to clear this room.
