A downloadable game for Windows

After several days mining in the old extraction site, you decide to return and deliver your ores for a nice treasure, but before, you will have to escape. In this game, you will go through the last corridor before your freedom but it will not be easy as you will have to unlock the doors that lead to the exit.

These locks don't use normal numbers but the moon phases. With this system, the phases that lead to a full moon are equal to an addition, and the phases previous to a new moon, substract.

Fix 1: game would crash with one particular operation. Also fixed a typo.

Hint if you need it: Select a button in the first and third column, and it must add to the selected button in the middle column.
