The Great:
Beautiful, addictive, fun, lots of variety.
The Less Great:
1) Levels are too easy, especially once you’ve trained heroes and upgraded weapons.
2) Levels are too short! Not enough time to build /a few/ advanced weapons before the level’s over. Would love a 10 or 15 round option!
3) Heroes can be difficult to maneuver in battle, often not responding or moving to the wrong location.
The utterly annoying:
Huge amounts of gems (money) needed to shorten the wait time for upgrades. A /full day/ to wait for an upgrade that I’ve spent hours earning already?! Come on.
