I have played the game Twice...
In my opinion, the game kind of feels, generic. The character/entity becoming more and more unusual towards you, the level design, and so on.
But it still feels, straightforward. The moment I saw the Entity in the real world, I got really scared. However it took 5 seconds for me to realise I had to switch the power off. And get out of that damned room.
The very moment I realised there was actually nothing outside the room, I just bursted into laughter. Realising how damn right that Entity was. But still, I will give you guys props for making a good OST, it did make me think I was in impending doom.
I would give this game, pretty much the maximum amount of stars that itch.io supports :3
Either way, this is a pretty good game for what it is!
