Energy Collector

Most idle games ask for your clicks. Energy Collector, by Jens Roderus, released in June 2023, asks only that you move your mouse. Energy spawns, you hover over it, it gets collected, and the whole game grows outward from that one softened verb into eight simultaneous playfields, an expedition side game and a prestige system. It is a minimalist machine for making numbers rise, and it knows it.

What the loop feels like

Each field behaves like its own small idle game, generating energies you sweep up by hovering. Early on you hover a lot; then the automation upgrades arrive and your hands leave the keyboard. That's Energy Collector.

Resources move between fields, transfers become the real puzzle, and you log off knowing eight little economies are ticking without you. When you come back, you upgrade the hub, tune the fields, pet your companion, and leave again. That's Energy Collector.

The systems doing the work

Systems stack in layers: energy levels and player level as the core meters, hub and field upgrades for transfer capacity and generation efficiency, a customisable companion with augmentations that follow you around, power-ups for playstyle specialisation, and a prestige reset for permanent gains. Occasional quests and an expedition side game that feeds back into main production break the routine, and there are over five hundred achievements plus hub decorations for the completionist register. Community advice is consistent: balance investment across all eight fields rather than hyper-focusing one, because transfers create bottlenecks; buy automation upgrades the moment they appear; tailor companion augmentations to whether you play hands-on or offline-heavy; and time your prestiges for when growth visibly flattens rather than the moment the button unlocks.

Where it stumbles

The r/incremental_games release thread is a fair mirror. The presentation is extremely barebones and fails to hook players who want an evolving interface, and several players questioned the value proposition against free web games with proven depth. The long-term complexity criticism has some weight too: prestige exists, but the deep multi-layer prestige ladders of genre staples are absent, so the ceiling arrives sooner than veterans would like. One player's defence lands well: for the price of a coffee it is fine, and fun early.

Playing it today

Paid, on Steam, Windows only, with Steam Cloud saves, leaderboards and a large achievement list. No verified phone version under the same developer. If you want the deep end, To The Core or Reactor dig further. If you want eight tiny economies purring in a tab-sized window while you work, this is exactly that.

The verdict

A modest, honest hover-idler that knows its scale: eight fields, one verb, zero clicking fatigue. It will not replace your main incremental, but as a gentle second-monitor economy it does precisely what it promises.
