Very funny game. Although some of the complaints can be considered legitimate, it's nice to see a developer who can look at it and laugh his rear end off. 5/5 for that.
Interesting glitch I just got. I had one of those axe horsemen, and it hit the enemy leader, sending him flying. I activated arrow rain and the arrows struck him and sent him flying off the screen. O.o
Also if you're having trouble, try farming the first few levels. It makes it quite easy once you have new game plus, as you'll already have advanced units and spells, so you can pretty much go do something else and your troops will fend off any enemy attack thrown at them.
Quite a few names seem to be adaptations of LOTR. Morgur (Mordor), Ravndall (Rivendell). Also yes, the creator has used some cliché units, but he has also included some quite innovative and fun ones, to boot.
The only real problem I have with this game is the level cap. 30? Come on, I hit that halfway through, lol.
Bradbury, perhaps it's a problem with your internet connection. I use a laptop (2GB RAM, dual-core 1.56mhz processors) and don't encounter any lag whatsoever.
