That's just too easy... Challenging on first 20-30-40 floors, and gets really boring then. All you need to do is going only for monsters you can kill with 1 attack, those who guard red boxes (not all of them) and those who guard jewels (most of them) and yellow boxes (ALL of them). Then u use best equipment u have, sell junk and buy as many potions as possible. And, other magic than heal is useless. Even if this game is kinda fun, it's just way to easy. 4/5 (I'd prefer 3.5/5, but since it's impossible...)
Weak. All I have done was making cash upgrades, making new footmen/knights and then defending once by once, making new buildings and constant rushes. No use of gunman, cannon, monks... And I did play on hard... suxx.
...the game is too easy... combat shotgun x3, some reflect shields... u make shields on, kill some enemy on close range (all 3 shots into him), then run away as soon as shield wears off... and repeat all times. Does not work on mines and rockets, but hey... u can destroy them! BOOOOORING.
