I was loving this game but I think its perhaps a little bit too punishing haha, I was liking the characters and story but ran out of money in the third day and couldn't continue. I think there should maybe be a bigger bonus to making a perfect drink, because usually the tip from making a perfect drink doesn't even cover the cost of ingredients. Though I'd understand if that's an intended mechanic to make the game more difficult.
I was really impressed with the length of the game as well, there's a lot of content for something made in 2 weeks! Also the character designs are awesome, particularly OH-4V.
