Good game, but kind of breaks easily. On my third respawn I stopped seeing bosses (they would briefly appear before exploding and giving me loot. Same thing happened with several waves of enemies, exploding off screen after a long delay of nothing followed by loot pouring from the walls). Also, the boss time counter up the top froze after I beat the first boss (only one I actually got to see). I am using Chrome on a mac, if that helps you work out any problems.
GAMES:
Gold Nuggets: Pretty basic. first level soil required. Click the yellow dot for money.
The Ant Game: Sand required. Use arrow keys to control the ant. Carry all green dots to the ant hole for some money and maybe a mystic crystal. WASD does not work.
Soiled Thy Memory: Highest level soil required. Click on the circle that has an arrow pointing to it to begin. The circles will flash in a series, and you then have to repeat the series through clicking. Double clicking doesn't work very well in this, you may need to pause between flashes for a double flash.
Why would you get the minigun? I stopped at x-ray. ended up with 100k + cash at end. only bought three guns (rifle, handgun, x-ray). With x-ray you can kill everything on the map in a couple of shots...
