Thanks, I am glad you liked it. Some jump scares would have been nice. As for your issues please see my response to BBIT's comments.
Ahh I see! Yeah I saw the stairs upwards as well but I wasn't sure how to traverse up?
You have to teleport up the stairs, it's a bit tricky and the reward is not worth it to be fair. Did you see the one at the start?
(T_T) Missed it!
