So I have played the demo and here is what I think about the game right now:
It is really fun but I feel like the game snowballs a bit too much.
There are tons of different strategies you can employ and most of them are viable if you get the right support, however something I have noticed repeatedly throughout the different versions of the game is that most of the time I can usually tell if I'm going to win if I get about halfway to the next target after the goblin enemy. From there I might lose 1 life from some random encounter and maybe another from the dragon but all in all the early game feels like it dictates the rest of the run a bit too much, it would be nice if the difficulty was a bit more even throughout the run instead of it mainly being how lucky you get with your starting units.
Once again, extremely fun game, one of the best auto battlers I have ever played, just feel like the difficulty could be a bit more linear. Also this was just with the newest steam demo and default play mode.
