Overall I think this was great.
Game mechanics are presented pretty intuitively together with the level design. I never really got stuck and I always get stuck in games lol. I hope there's more game mechanics with light physics.
My main complaints are bad stuttering in 1-2 areas and a better way to engage the story/world with the player. I (think) saw an NPC and just wish there was some way to interact as a way to encourage some exploration.
