I beat the game by walking around and spamming E while cleaning the money every time it popped up. I honestly didn't really understand what was happening, or how the suspicion meter worked, or how the dirty money appeared etc., but I guess I did enjoy it. The visuals and voices are really charming, and the storyline is kind of hilarious xD
I have a feeling there was a lot more planned for this game that didn't get done, which is understandable, e.g. I feel like the day/night cycle might have been a bit unnecessary as I found myself just waiting around for the store to open again. But now that I think of it, it's probably a good strategy to save the dirty laundry until night time and clean it when the store's closed. So maybe nevermind that comment.
Anyways good game overall, I liked it!
