It's ok but
It's ok but the controls are awkward. I wish it were just so that left is left on the map, right is right on the map, up is north, down is south, instead of the type of controls where you rotate. These hard controls and at the same time needing your good hand to control the mouse, is really awkward.
Also, everything went well, until there was a level "collect 20 vitamines". I killed every enemy and had 3 vitamines. Scanned all of the map, found no other vitamines. At that point I gave up on the game :(
Plus I was constantly waiting for a sort of upgrade that would let me do more damage with the "spike" but never got one. Wasted some points on upgrades that turned out to need 15 EP's in a path I didn't want to spend these in, without knowing that beforehand.
