To make a good horror game you need one mechanic to make it look profesinal, ADD A LIGHTER yes its pointless but the amount of horror games ive seen have a lighter its just that thing that horror games have. btw good luck!
IDK if that is necessary, the game should just be 1 room, and a big (huge in the middle) lighter that omits no light. Then do some spooky sounds, bam, horror game.
i know its not necessary but it shows you put effort and time into your game this will please the judges. also ur idea will get u in last place there should be more to it
I don't think this would be any more effort than adding some texts (dialogues) or having some interior design in a room. I believe horror games relies more scary sound effects. Candle is a good asset usually but not a necessity in my opinion
