what is OSTM?

Level up and explore new discoveries in this idle RPG clicker game.

OSTM is an idle clicker game with RPG elements where players level up and uncover various features. The gameplay involves gradual progression through repeated actions and exploration.

It sits in the Clicker / Idle / Numbers / RPG corner of the genre. Like most idle games it runs on a simple loop — earn, reinvest, automate — but the depth is in how long that loop keeps unfolding. Expect to check in, make a few decisions, and watch the numbers climb whether you're at the keyboard or not.
