I'm super happy with the current state of this demo, and I hope everyone else out there who gives it a shot will also enjoy it! The only snag I think some newcomers are likely to hit is if they are a bit confused on how to strategically place their units if they are going in blind. But hopefully they check out those tutorial tips in the corner of the screen and learn something from seeing the pictures I left in there.
That's pretty much the best advice I can give for anyone trying out the demo for the first time, lol. Clump a few of your units together so they all can receive some heals, and put ranged attacking units like wizards and archers behind to back them up with some extra firepower! Sprinkle a few Thrower units like alchemists, bombardiers, and pickaxe throwers around to deal with the flying units, and you're good to go!
There's your obligatory call to action =]. If you enjoy the demo, give it a wishlist and be on the lookout for it, maybe even in the next month in time for Steam Next Fest, if all goes well!
