This was a frustrating experience. Not being able to see what my surroundings are was bruh. When she left for a smoke break it was kind of dull because I thought "Oh, I'll have a guide!" and then it was just a straight shot to the end of the level.
You did a good job introducing mechanics though, so that's a plus.
I couldn't figure out how to do the last puzzle, but I stumbled upon a glitch where if you clip into the block by jumping and placing it below you, you skyrocket up and can get over the wall. (I clipped out of the world at one point lol.)
Overall not bad. Good job!
