SPOILERS AHEAD!
There's a lot in this game, the gameplay mechanics seem to be well designed, I liked that you need to rest every once in a while and don't use the flashlight too much. I didn't complete the game yet, but I found the arcade, kitchen and dave the microwave, and at least I managed to complete the arcade secret game. I'll probably get back to try and complete the game and also to unlock some more secrets. It seems like there's a lot of those.
It is kind of mechanics-based game, kinda reminds me of FNAF type of game where various evils are doing different things and you have to take care of them. At least that feeling flew over me when listening to the radio for the MicroHorrorArcade game. Which is not really my cup of coffee, but I'm glad the main game only has focus on Boofie, cause it's really more than enough for me at the moment.
A few things I had a little problem with. Sometimes it's hard to tell which key I need to find, the lock seems white but then the white key doesn't work, also the red lock seems kinda yellow and that threw me off a bit too, maybe it's post processing messing with me. I also didn't really like that when I drop the key I never know where will it appear, sometimes it goes to the original position, sometimes it seems that is just vanishes from existence :D
Other than that, all this secret hunting gives me a feel that the game may or may not be oriented towards youtubers mostly, but the game has a ton of content in it and it seems well made as much as I've seen while playing it, of course the dev has played a million horror games already on youtube himself so yeah, he knows what he's doing.
