The game is a 8/10 i would say.
Visuals are cool.
Story is cool, although you have to really pay attention but i guess it's not hard to understand that...SPOILER_STARTthe protagonist suffers from schizophrenia, atleast that's my take on it. And boy oh boy i think they actually conveyed it extremely well of how it might be.SPOILER_END...
The controls are fine i think.
Now keep in mind this is a psychological horror game. You will not get any difficult puzzles here. It's really about the protagonists "story" that they want to display here and make you catch a glimpse of what it might feel like to be the protagonist. Most of the time you get the solutions thrown at your face, but there is one part in the game where i felt a bit confused. That's also where my controls went a bit funky. Not sure why. SPOILER_STARTNow i don't fully know what the game is called in english but it looks like chess, however it is only using flat circles as the stones. So maybe it's called "checkers" or so. Anyway, when there is that checkers board in the center of the room you will have to collect pieces of the boardgame which took me a bit to understand. And once you finished it you had to walk back to the table on which the boardgame was to progress. That's where i had the problems with a rotating camera and the sound not being played on both ears in stereo-fashion.SPOILER_END
One improvement i suggest is making the player more aware of where to look. They used the enforced-camera-look but when some vital things were happening i scurried too fast through the door or looked somewhere else and completely missed the action.
Now one thing i really didn't like is the sound design. It's not the sound itself but for some reason when i played this with my headset i could either hear directional sounds on the left or the right ear. Meaning, if i was in front of a door, or a drawer i would have to look a bit offset at it to get the sound played. And if i looked straight onto anything that has directional sound i would not get the sound at all. For example a piano, when it played an i looked straight at it, i couldn't hear it. If i turned the camera a bit to the left or right i was able to hear it but just on one ear. I suppose that's on unity. Or maybe my headset. Who knows.
And another bug was that my camera just started rotating for no reason and i was unable to stop it. Maybe that was also on my side, but that can happen i guess.
Apart from that i would say a solid game. But in my honest opinion i wouldn't have bought it for 20€. Maybe 10€. It was on sale when i bought it for 1,99€ and to be honest a game like this for 2€ is really awesome. More than you can ask for. For 20€ i would say, polish a few things. Especially the sound design. And maybe guiding the players camera more in rather vital moments.
