Planet Buster

An idle clicker with a destruction theme and a more interesting upgrade tree than the genre usually bothers with. There are several independent statistics — raw power, gravity, how often projectiles spawn, accuracy, and what you earn while away — and because they multiply against each other rather than stacking, the right purchase depends on which of them is currently behind. That makes the shop the actual game. Spending everything on power produces a character that hits hard and misses, and spending everything on spawn rate produces a stream of projectiles that do nothing; the efficient path keeps them roughly in proportion and then pushes whichever is cheapest to improve. Offline earnings are a real upgrade line rather than an afterthought, which changes how the game is meant to be played — in check-ins rather than sessions. Progress carries across worlds, each tougher than the last, and the numbers get large in the way this genre requires. It runs in a background tab, saves reliably, and plays one-handed on a phone. As idle games go it is on the short and well-paced end rather than the endless one.
