Great game! I do think the melee units are a tad underpowered, though. I played with ranged at the beginning, and it was incredibly easy(the darn lancers were annoying though!), but when i later tried playing with only melee units, it was incredibly hard and they would usually get lancer'd and ganged up on easily. Perhaps increasing the number of Barbarian/Hammer Dude faces would help. I think having something like a new melee unit would be very nice, perhaps a buzzsaw as an upgraded version of the wooden stakes that moves forward, or a super barbarian unit/even bigger hammer guy that launches enemies back. It'd also be interesting to see a way to have more of an in-game presence, since after a while you can place down a bunch of ranged units, and then just wait, occasionally lobbing bombs. Being able to possess certain bosses you kill or something and directly controlling a strong unit would be really fun!
