Downloaded this last night, looks interesting... but I can't figure out how to play, really. The interface is simple enough, but actually figuring out what the heck's on my screen is bewildering. Took me twenty minutes to realize that there were two different types of terrain, and one of them, my squads could walk on, the other... they went a little ways into and stopped, except for the occasional time when they didn't. And except they didn't really stop, they just kinda milled around aimlessly, further confusing me since there was no demarcation of any sort to indicate that they'd hit a barrier.
Trying to get my squads to fire grenades, sometimes they go flying far, sometimes they land right next to them and blow up my squad, no matter where the cursor is aimed. In the same spot, they won't go over terrain that previously has been easy to walk across.
Can't see the viruses when they're on a white terrain without zooming wayyyyy out til all I can see is the viruses and the basic shape of the level.
So. Is this a performance issue? I poked at the graphics settings, nothing seemed to change significantly, (except it was harder to see anything at all on low settings). Is this a comprehension error; do I need a better tutorial? Is there.... wind, or something, blowing around my grenades and units? Or is the game just buggy? (Not something I'd generally expect from Ambrosia, at least not by the fourth version.)
