The pitch is simple: Google Play Points rewards quests in games, and this bot offers to finish them for you. We're wary of it. Automating rewards very likely goes against the program's terms, and what's at stake is your Google account, the one with your email and purchases. If you try it, go in clear-eyed about what a mistake could cost.
Two commands are all you get in the chat: start, and share your tokens. A token is basically one go, and the first is free. How you get more, whether by buying or inviting people, becomes clear after you start.
How the bot actually completes quests and connects to your Google Play profile isn't explained. The description only says everything syncs directly and points land in your balance. For a service that needs to reach your Google account, that's very thin.
On risk: Google Play Points is a loyalty program with its own rules, and rewards earned by automation rather than play can be reversed by Google, with the account restricted on top. Words like safe and fully automated don't settle anything here, the bot isn't the one deciding. And as a rule, don't give login details for your own account to any third-party bot.
There's a single owner listed, a private person, and nothing else is said about who runs it. For something that touches your main account, that's a reason to wait.
