This is a VERY unique concept. Like, artistically, this idea is absolutely fantastic.
The game's intro reminded me of Portal 2 intro sequence - and it was awesome.
I loved the gameplay - it was tense, but forgiving with the amount of health you had.
The music was absolutely great - I really loved the tune that played during gameplay, it was very catchy, and the theme in the intro set up the mood perfectly.
Nice job!!!
