The fact that your guys can't shoot anything, and stop moving before they get to position makes the 5th challenge too difficult to be enjoyable. Nice graphics, but needs some game-play tweaks. 3/5
Not bad. The inability to switch from freeze to regular gun is a bit of a problem (until autofire upgrade). Also, I didn't see any progress being made on the "wake up" when I was pressisng the space bar. Maybe a glitch? (I was using mouse to control firing.)
After the game wouldn't load, played it on another site. Got 5 $!
Tip 1: fuel, hull, drill until you get to the emeralds, then go for the mole and turbo.
Tip 2: use the mole once it's lvl3 to take out the rocks in front of you.
Nice job. A list of what combinations get you bonus kills (or something) would be helpful. For instance, the electric gun gets better for killing crawlers, but I don't seem to get bonus kills for killing them...
