Tower Hero Wars
Tower Hero Wars is a brain-first battle puzzle: move your hero between platforms, pick fights only when your number beats theirs, and grow stronger with every victory until the tower is yours.
The rules fit in one breath — defeat enemies, increase strength, defend your tower — but fight order is everything: the same map is a rout or a wipe depending on which enemy you visit first.
Tip: always clear the smallest enemies completely before touching a mid-sized one; leftover weaklings are free strength you'll want later. More of this genre under superhero games.
