So firstly, I dont really play many horror games, and usually when i do its more psychological horror. This game really nails the eerie vibes, whether it is the artwork, music or the creatures having different personalities. I cant really say much about what can be improved but i can make some suggestions which may or may not be good. Firstly, i think having some "fake" noises would be quite nice, like a rabbit or bat to give some fake ambience. And another thing would be to add one more mob, because i think even though the 2 is enough, by my 3rd life i got a bit used to it, and one that only spawns when 4 items collected would make it scarier. But its for more hardcore players i guess.
I did encounter 2 bugs, i dont know if this is to be mentioned in the review, but ill say it nonetheless if it can be of any help. One was that the game crashed when i saw one of the entities, and the other, i got trapped in a tree and when i crouched i went under the map.
Overall i enjoyed the game a lot, i think a few more levels and a bit of story, I can see myself buying it on steam.
