Yo I played this in class so I'm just gonna write feedback similar to what I said in class.
I think the jump is a little too high. You hit the ceiling every time you jump, and it makes it feel a little unnecessary.
Some more decor would be nice to make it so the player doesn't get lost. All the rooms with the exception of one look exactly the same.
Feedback on if an activator is pressed, either by changing color or a sound, would be nice to let the player know.
Overall its pretty good but I think a few extra tweaks would make it a much better experience!
