Good game. Nice mix of tower defense and offense. It was a bit tricky to figure out where to place towers. But I was able to make progress and place towers pretty close to the enemy base. Also the towers need to be protected by warriors. With that and HP regenerating, it was only a matter of time. Soon I was able to spam towers near the enemy base and win. But the towers are weak against the enemy, so the warriors are always needed. Actually didn't bother going back to town for the upgrades :) The concept is pretty neat, and the two different types of units (towers and mobile warriors) is pretty good. For future you could consider general balancing and variety of enemies. Well done overall!
