Took me until near the end before I understood the intricacies of how the swapping and teleporting worked, and I couldn't figure out what to do after I got the knife even after I read another comment about orbs. It wasn't until I just happened to wander back to the start and saw the orb there that I remembered it existed. Walking around, getting teleported unintentionally, and losing my orbs ended up being too tedious for me to complete it.
The mechanics have a lot of potential for sure, but they're not yet clear and concise enough, and the game could use more quality-of-life I think. However, the sprites. ambience, music, and sounds are all great, and definitely encouraged me to keep trying longer than I probably would have otherwise!
