Love the game and idea I have some suggestiongs and addond to help improve the game further.
1: Having the Ayuwoki crawel on walls & look over couchs when the player is hiding behind them. ( Most of the times I were scared were not from him attacking me but looking at me and knowing I'm there but waiting because he knows I'll be out again.)
2: A possible weapon like a gun that is hidden around the house you would need to find the gun, clip, and a bullet to kill the Ayuwoki but you only get one shot. (Multiple endings and the helplessness if you misfire that gun)
3: More areas and maps!!!
Keep up the great work you have something special here!
