About Planet Gemini
Planet Gemini is a factory-building and tower defense game. After crash-landing on two planets during an interdimensional journey, fend off waves of enemies and research a portal to survive.
FEATURES
- Two Planets: Teleport between two planets with different resources, and build bases to defend against enemies.
- Co-Op: Managing two planets alone isn't easy. Team up with a friend in 2-player co-op and take on harder difficulties.
- Factory Automation: Gather resources and unlock technology to build more efficient automated facilities.
- Tower Defense: Build defensive lines with the resources you produce and protect your base.

Just weird and really lacking in a tutorial. 3 buttons to get logs from a tree seems incredible silly. its good for the price. but really lacking in polish or charm5 found this helpful

I like it. Similar to Satisfactory if it were 2d. Also, contradictory to what the negative reviewer says, there is a tutorial in the upper left of your screen.2 found this helpful

The game is fun. It has some kinks.1 found this helpful
A fun game with good bones, there's a bit of jank here and there but it's amazing seeing what's being created. The two world approach is awesome, and I'm having a blast1 found this helpful
