I am confused on what you are selling.
Spammed ai slop. That's what's being offered. Two projects a day. Come on. This is the type of "developer" that makes people hate ai, and for a good reason.
The game is entirely playable in the browser so there is no reason to buy.
That's not the reason to not buy. It is actually a common incentive to buy a browser game: you get the download version - even if that download version will still run in a browser on your computer.
Technically, a browser is a game engine. We are just not used to seperatly download engine and game anymore.
