We are UltraVal or in other words @ultrayoshi and @ReikVal (original, uh?).

Inspired by Minecraft and Spelunky "Speluncraft without crafting" is a game developed by Ultraval team with cool background music, an infinite map and dangerous lava!

How to play
-----------

Objective: Collect as much money as you can without dying.

Move your character using A and D keys. Use the arrow keys to dig but be careful, some materials need more than one hit. Finally, jump using the spacebar.

Randomly, a Warning signal appears and lava starts to emerge. Move your character to the surface in order to survive.

If you go deeply you will find more and bigger treasures but the probability of danger increases as well.

Some materials are more durable than others. Use your pickaxe more than one time!
