Idle Asteroids merges arcade shooting with incremental progression, asking you to survive waves of asteroids while building up weapon upgrades and passive defenses that eventually let your ship run itself. The core loop alternates between active combat and idle accumulation, with persistent upgrades gradually transforming your fighter into a self-sufficient mining vessel. Best suited for players who enjoy both hands-on action sequences and the satisfying automation creep of idle games.

A fun little idle battler - it does what it says on the tin.
When in idle mode, ship does a pretty convincing job of dodging and attacking, impressed with the coding, given how chaotic the screen can become with asteriods careening all over the place! Costs about the same as a cup of coffee, so can't really go too wrong here.
Disclaimer: I am friends with the developer, but tried not to let this influence my review
Update — Performance & Weapons Polish Performance Shrapnel pooling — Multiple asteroids shattering at once (e.g. from a nuke) no longer causes frame drops from mass instantiation. Adaptive quality tiering — Changed the thresholds to reduce effects when FPS start to drop. Singularity — Batched drawing to speed up the rendering of these. Shrapnel — Cached some math at spawn instead of recalculating every frame. Gameplay & Fixes Shrapnel included in blast calculations — Mines, missiles, and force nukes now properly destroy shrapnel within their blast radius. Gamepad disconnect handling — Disconnecting a controller now rescans for remaining devices instead of assuming none are connected. Population safety caps — Added maximum limits for bullets, missiles, mines, and singularities to prevent runaway spawning. Most players should never hit these limits As always, thank you for playing Idle Asteroids!
Minor Patch v1.2.2 Performance Smoother play at high rounds and levels, found some optimizations for enemy tracking, AI targeting, and visual effects. Cleaned up internal object tracking to cut down on some wasted cpu cycles. Gravity Wells Missiles can now damage gravity wells Gravity wells slowly regenerate HP while caught in a singularity's pull Slingshot launches more accurate, beware! UI New FPS counter — press F to toggle it on/off As always, thanks for playing
