This was a fun one! I liked the premise a lot, and the art style and aesthetic are very pleasing.

I really liked the idea of hearing someone's heartbeat to see if they're lying or not. I think it'd be cool if that was expanded upon or used as a game mechanic in some way. Would definitely love to see what you guys could cook up with more dev time, whether it'd be something similar to this(like a sequel or longer version of this game), or a future project in general!
