Hello there, the game is a pretty solid project and i like the PS style and all the features as the photos and flash that scares the monster. Altough i think the monster AI might get a small rework, i would suggest to add a sort of holes, vents or places where the monster would go when caught lacking.
Also i would make it a bigger project remaking it on unity (if possible) so you can work on a more flexible engine and to make it a full game. I would really like to play the full game.
I really guess that you took the ispiration from game MOTHER, if not, i hardly recommend you to check it out since you got many mechanics that are very similar
Thank you for the early review on my game, i really appreciate your time spent on my game
