Geo Survivor

Geo Survivor is a geological roguelite.

Your hammer is your only weapon and tool.

Hammer upgrades
Collect, combine and find synergies from over 200 hammer upgrades.

Mana Powers everything
Your upgrades convert mana into useful skills to defend yourself, traverse the caves and mine rocks and minerals.
Mana can be generated or accumulated from a large set of sources. Define how mana is flowing through your hammer. Be creative when in comes to decide what skills and combinations will make you survive.

Find exploits
The game explicitly wants you to find positive feed back loops that will make your hammer overpowered.

Procedural Cave
Traverse different geological biomes like the limestone caverns or the volcanic rhyolite intrusion.
Encounter large creatures that can only be defeated with a clever hammer build.

Meta progression
Spend rare purple crystals to permanently keep upgrades from runs to develop your personal hammer over time. 

Engine
The game was made using zig and raylib, on top of which I wrote a small and simple custom 2D engine.
