First time around, I couldn't find anything to do. I missed the part about hitting tab to shift to the other dimension. I ended up restarting to figure it out. Second time around, it took me forever to find all the red orbs. I didn't know how many were left and after I hit the last one I kept wandering around, only to tab out and realize the keys had already spawned. It ends abruptly when you open the door after getting all the keys. I did like the aesthetics, with the items floating in the sky to give it that dreamlike feel. Great job doing this solo!
