The aesthetic of legally distinct Aperture is really cool (my favorite part was how the opening letter was signed 'Cavern Johnson'), and the idea of turning unintentional softlocks into the main mechanic is very interesting and ends up being a lot of fun. The visuals in general are quite polished, but one thing I would like to touch on is the gameplay - I ended up softlocking Chamber 2 both by throwing both cubes out the observation window and by throwing one cube through the door.
Overall, great job! This is one of the most polished games I've played so far.
