This is nice, I finished the game with 21 dudes. It’s a simple mechanic but what is implemented is very well done. I think some animations for running and fighting would go a long way towards making this game really feel awesome. I like what you did with the thumbnail btw, clever way to make the characters pop, I need to remember that one.
All in all good game, great work. My game is linked below if you want to check it out.
