Gemini is a fighting game where you defend a Crystal from waves of enemies. It's super simple in both visuals and gameplay. As you defend each wave you can collect coins to upgrade your character and purchase weapons. It's a great introduction to tower defence style play for younger and new game players.

Gemini has 5 different worlds, 25 levels, and 125 waves. More unusual is the depth in weapon choice and customisation for such a simple game. You can unlock 64 types of equipment and upgrades. Add to this the large range of monsters, bosses and loot and it's a great little package.
