Lava Collector

You are a Lava Collector.

In the far future after humans, robots farm powerful crystals that can only be collected from exploding volcanoes. You must use your skills as a Lava Collector to dodge incoming fireballs and collect the valuable crystals. Watch out! If you stay too long, whatever sleeps in the lava with be there to defeat you. 

Collect crystals for points. Crystals, also, charge your stamina and attack power.

This game is a work in progress. 

It is my first game and I welcome any feedback.
