This is fantastic! I love the cute little story and the visuals are fun. And I definitely didn't expect the goofy sound effects when the townsfolk carry the hero! The gameplay is also well designed with some legitimately good levels layouts. The only things I would look at if you take another pass at the game are minor and include showing the path that the units that are already placed, keeping the units placed when you fail, and making it clearer when you can't start the simulation because there are no units touching the hero. (That took me a minute to figure out. Lol)
That being said, I truthfully enjoyed this game! I hope you take the concept further in the future!
