Are you able to give some more explanation of how to play? aka do anything but move.
Oh yeah, of course, in the game you have to collect 100 of energy (mining a "white" stone pressing J or Z)
In some cases you will enter in combat mode, in that case you have to move the aim to shoot the enemy
In the spaceship you cam buy ammo or velocity to aim btw
this is basically this, I made the game in less then one day :)
