I admit I'm not a fan of clickers so I'm not really the target demographic for this. Like others have said this is definitely solid in terms of not being clunky or buggy and the setup for the "story" is kinda funny.
The things I'd suggest is mostly things that would come up through development anyways. There should be more things to buy at different tiers, there should be maybe some sound effects or music added (there wasn't any sound when I tried it atleast, maybe that's an issue on my end), and some animation on the conveyor belt perhaps would add some visual flair.
The only major issue I found is that it was kinda easy to cheat the game by simply clicking on the loose change button once, and then just holding enter. This triggers the button continuously for as long as you hold down enter, so I was able to rake in several hundred dollars in a matter of seconds.
Also it didn't seem like robots helped after buying a few of them, I got up to about 70 out of curiosity and it didn't seem any more effective than 20 or so.
Overall, not bad.
