I wouldn't call this game a hidden gem, but it is very close. The game turned out to be kind of addictive and charming.

I think part of the addictive quality is that there no hand holding, and you have to figure out the games mechanics on your own. I mean, there are little hints here and there, but you mostly learn by trial and error. The good thing is that it is not too punishing, and restarting after a game over is not a hassle.

The gameplay is really good, with simple controls. I did wish I got some things explained, because I still didn't understand some of the enemies, dimensions, walks in the forest, etc. I was just trying to progress in the game, but didn't get a lot of it. Knock Knock has a story, but I kinda missed it. Probably I didn't find all the diary pages and other sources of lore. I think this could have been exploited more.

The art style is so beautiful and well put together. Lately I have been enjoying games that look like cartoons. And the sound! You definitely need to play this with headphones and use the sound as cues. It is part of the gameplay.

Very creepy and charming game. I enjoyed it, even though it was short and I didn't really understand it.
