I would have been more than willing to buy a non-free version of this game without the pay-to-win BS. You could have made it right and called the Kong version a 'demo'. That's how I bought Creeper World. This lunacy with allowing users to spend the equivalent of $100 on uncut dice... you're not going after a mainstream market, there, you're just preying on stupid people. That's really not cool, and I doubt it's as profitable as just selling a game normally.
The reason you're surprised anyone uses the keyboard shortcuts is that you didn't put them in the tutorial. Also you bugged it so that the user has to wait a few seconds before pressing '5' will work, for each character (where clicking works immediately).
I propose you create an ending at roughly where you would expect a whole planet to be converted (whatever number 10^50 atoms covers) and show an animation. Animations at exponential stages would be even better, like a guy pukes and is slowly converted, then a city... Just letting it go forever is a bit of a letdown.
