The newly released game, Slime Squisher has a bundle with Just Click The Button!
You can purchase the bundle even if you already own Just Click The Button. This will make Slime Squisher even cheaper!
Both games are roguelikes, clicker, bullethell/heaven and arcade games. They share a lot of similarities, BUT they are played quite differently!
