OMORI is a beautiful must play. The game features strong topics and handles them brilliantly. Around 12-15 hours in the game might drag a tiny bit, but once you get through it the game just keeps getting better. The horror elements will have you sitting with a "what the actual ♥♥♥♥" expression for most of the horror elements. Exploration was a fun time especially due to the extreme variety in the NPCs. The story just reels you in and makes you want to continue playing.
Overall the game is amazing.
