The option to sell upgrades would be appreciated so that I can get rid of the useless riflemen. Marksmen and Rockets are the only useful endgame units.
Some control over the opponents, skills available, aggression, and map size would be much appreciated in Skirmish mode. Every skirmish I've played so far is too easy.
Very good game. Ignore the people saying it is too hard because they probably didn't take the time to learn the patterns. Too easy once you know all the patterns.
My only complaint is that once your armor is upgraded the shops still appear. You should still be able to buy armor even if it only heals you at that point.
Very fun game. My only complaint is that at the end I had looked at every item in every shop and never once bought anything. My items were always on par or superior. I never even felt the need to use a potion. I went the necro/arcane route and owned everything including the final boss and was disappointed that I still had items I couldn't use yet do to stat requirements. More godly items that I can use please!
Levels go on forever (although the text would cut off eventually). What fun are character advancement limitations? :)
