Nice entry! The graphics are really good and got me intrigued from the start, but the game felt too easy. Since you already have a menu system, I think it would have been worth it to parametrize the attack, speed and HP of the enemies and have a difficulty selection menu at the start. It's always tough to balance jam games, but this way you can just have three levels of balance and with some luck one of them is gonna feel right haha.
I really liked the walking animation on the enemies, it's a little thing but it's really efficient. The attacks both from my minions and from the enemies were clear enough to me. I do wish Archer Skeletons were able to shoot over the holes in the terrain, would feel really cool. :)
Really nice job on the audio as well!
Again, very nice entry, confrats on making it!!
