I loved the dialogues! Also the way you made all the suspects feel real and with their own motivation. Also was really good that you made an objective indicator! The child scared the hell aout of me lol
SPOLERS AHEAD:
Although I already know the truth, I'd love to see a bigger version in which the killer lead you to different "false culprits" paths, depending on who the player suspects and what they aim towards. It would be a even bigger gaslight, since the player already suspects it. Maybe the jam ending is the one when the killer is the main suspect!!
Anyway, nice work XD
