Neat idea very atmospheric. The music is very serene. I had difficulty with figuring out the controls because controls weren't responsive and it felt laggy and a bit inconsistant (switches wouldn't activate when i pressed them' and i couldn't consistantly grab onto blocks. Also i would appreciate a way to rebind the controls as i was probably using a different keyboard layout making many of the controls unintuitive for me. Also i would appreciate an indicator of where the light is going to come from when a switch is pressed. because i died a fir few times when switching the light which can get irksome when in a longer challenge.  and a nice quality of life fix would be if your character moved aligned with the axies of the world rather than 45 degriees offset from them. but this would be less of an issue if the performance was smoother.
