If there are any updates for the promised Steam release, it'd be nice to have a bit more balancing for the orc and goblin classes and other units. Taking a unit to the library and getting Courier/Tamer or Ninja/Healer at the start of the game and having to restart the whole run because of how much harder those are to use than just a single Warrior/Miner, an Engineer, and infinite archers.
Maybe a way to increase the undead or monster units' move speed? Or more perks that effect any unit other than Goblin Archers? As things stand, spending time and money on any class other than Goblin Archer in endless mode feels like a waste
