Not much to it.
Instead of not letting you buy things you can't afford, you get negative money.
I've no idea what the upgrades do or even are.
The word lollipop is misspelled in the game and title despite being the entire focus of the game, and the lollipop itself looks more like hanami dango 🍡 dumplings.
Trophies don't work- which, as has been pointed out by other reviewers, is completely possible to do in Turbowrap.
It seems impractical to create customization options and a code input system before the base game is complete and stable.
