Well that is fun! I've spent some time messing around, picking and interacting with stuff, before realizing there was also a goal. :P It's so cool to have this much details everywhere. The game has its own universe, very pleasant to discover.
Actually playing by the rules is fun too! I wasn't sure at first how to properly give a product to a client (“If I put it just there, will they be happy? Should they react? Maybe if I put it on their head?”), but once I got it, throwing stuff at them felt definitely nice! Main issue was picking the money. Without a mouse sensitivity setting, it was quite hard. I also wish I could interact with more instruments.
It was really cool to play! Great work here.
