TODO
- x add hard mode
- x just phoenix left!
- ? after being hit by hex, creeps attack
- x serpant wards are not air
- x dragon has no tooltip for incinerate
- x sky-fury op
- x firestorm range is low
- x gryphon rider perma-stun is too stunny
- ultra towers:
- mountain king: insane knockbacks and explosion deaths
- blademaster: dashes and ultraviolence slices
- dreadlord: mass sleep, mass life-siphon, souls accumulate and burst out
- demon hunter: 10,000 damage short-range attack; after attacking, bursts up to 3x finger of pains that instagib targets
- x 215 gold for orc hero tower builder is too steep
- x rifleman and sorceress are not "organic" units
- x crypt fiends should have web
- x ghoul tooltip indicates that it can fight
- x unholy frienzy has an annoying hotkey
- x blood mage is not an organic unit
- x tomb of relics doesn't have "select user" for shop sell
- hero dummies all have the same hotkey
- Altars all say "summons heroes. Revives slain heroes"
- it's a legit strategy to buy hard mode just for mazing -- make it more expensive
- multiboard has no title when it's not hard mode
