I'm just... not impressed. It's good for a 72 hour game jam, but the "Twist! You are the monster!" has been done to death. The date puzzles are tricky for players who use the mm/dd format instead of the dd/mm format. Also, I'm not a fan of having to look outside the game for clues that have all been presented inside the game until the last puzzle. Even if I had thought to go look up the number of atoms in potassium nitrate (I didn't), I probably wouldn't have bothered.
Overall, it's an okay take on the Orange Soda creepypasta, I guess.
