As far as I can tell there is no game here. What preview of a game there is is very poorly done.

I'm reading that crucial aspects are gated behind keys on a keyboard that don't exist on mobile. I'm assuming that's why I've spent 10 minutes getting plates to level 6 and over $5,000 which I can't spend.

What little "game" I've seen is also done poorly. You need to clean 10% of the entire surface while cleaning more by deep cleaning half the plate doesn't count. It should be 80% of the 'mass', which you can upgrade your scraper to clean it better and faster.

This is less of a game and more a venture into pure frustration and mild rage. That said, if the dev cares enough to fix the glaring issues it could be a great game.
