this is really well developed for a jam game. enough unit variety, ai that doesn't feel too dumb.. it was pretty hard for me to play and it didn't feel like it was just because the enemy's damage value/health is too high or something. of course you can figure out ways to break the intended way of playing the game and make it super easy for yourself, but that's no fun
the big tutorial dump felt a bit intimidating, sure, but there isn't really all that much to learn before you start playing, so it's just a first impression kind of problem. it's not really that bad imo :)
my only real "problem" is that the current color scheme makes it a bit hard for me to tell things apart and easily understand what's going on
