hehe this is quite fun. nice and simple. but, a suggestion: show the physical map always - just keep the fog for your enemy's position (like Relic's RTS's - not Blizzard's). also, it feels way too slow, but i understand why you did that. perhaps you could make the map bigger...so you'd have to add scrolling.
all in all, i love the tense simplicity! maybe a short-burst run mode (like NBA jam) would be nice too.
cool stuff - really enjoyed it! but..i really could use a save feature! i can't get through this in just one sitting..and i can keep my browser open for only so long.
