This game has a very interisting mechanic and i love it but i would say that it's not visually appealing. The game might need some more polish and better sound design, i like the lore you tried to imply by escaping the facility, it reminds me of portal, but it feels way less dramatic than it should be, because of the lack of fire sounds, alarms, music, etc.
Anyway you did a great job mate, keep it up !
