Lovely aesthetic and concept, I really like the dungeon environment since it goes hand-in-hand with lockpicking. I had some issues with the gameplay which admittedly is partially on the browser. The general slide-y jumping movement was fun, and I liked the idea of having the teleport. I didn't feel like the parkour-ish movement really meshed with the lockpicking, more like they were two fairly opposing ideas that got slapped together, since of course the movement and the chasing shadow wants you to go quickly, but the lockpicking (aside from just outright stopping you) really forces you to slow down and take your time. Maybe I was just bad at it, and it's possible to pick the locks smoothly/quickly, but I couldn't get into any kind of rhythm with it over my attempts.
Some little nitpicky things: I feel like the orb's hitbox was a bit too punishing, and the gaps to throw it through a bit too small. It just bounced off the lip of the gap 90% of my attempts which *was* a skill issue, but I didn't feel like it needed to be a skill-check in the first place :P I also wasn't super stoked about the "recall" not being instant since it doubled down on punishing those mistakes. I also felt that the game badly needed some kind of feedback on the teleport; I got disoriented by it pretty much every time :D
Great job overall, though :D
