Without any instruction I immediately tried figuring out what the controls are, only to realize there isn't any for most of the game.
There's a bit of an art style clash between the daytime and night.
Stat leveling is very straightforward so that's good. I only got to the third day so I'm not sure if there's any rhyme or reason to what stats you decide to upgrade (ie if you buy more balls before gaining more skills, will you drop them or something?). Maybe if there was some commentary from the crowd, like "only one ball? lame!" to hint to your player that they need to buy more balls before research. You did good showing the effects in the form of extra money coming in, but not specifically what changes cause that effect.
Most of the game is idling watching the clown, which personally didn't appeal to me. I thought it might be okay to run in a side window while I get some work done or play someone elses game, but this one freezes when you aren't focusing, so you have to actually be engaged with the game window even when you can't actually do anything. iirc Unity does have settings to allow games to continue processing even when they aren't focused.
