A HTML5 remake of an older Unity-based reactor incremental game.
Reactor Knockoff is a remake of an older incremental game originally made with Unity, now available in HTML5 format.
It sits in the Idle / Prestige / Numbers / Management / Sci-Fi 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.
