About Optiminer
Optiminer is a minimalist incremental about mining radioactive materials. Dig through the rock to extract raw ore and radioactive materials, then pour it all into a branching upgrade tree and go deeper.
Key Features
- Get shards to reach the next depth. Find uranium shards to power the elevator and keep the session going.
- A branching upgrade tree. Spend refined material on dozens of upgrades that reshape how you mine, refine, and progress.
- Minimalist, abstract presentation. No clutter, no factory sprawl: just a clean loop of harvesting, refining, and upgrading.
- Estimated playtime: 4-5h to reach endgame
