I think, most of the heroes was balance (I didn't test them all), but you might want to fix the experience, it is set in global. You can level even in base.

The creeps, was kinda out of control and overpowered. There are too much creeps, in first wave, your hero can level up to 3 levels. Plus, the creeps can easily destroy the towers (Or base), maybe in 3 to 5 waves, the towers are destroyed.

Item is looking good, nothing much to say about it, every item needed is in the shop, such boots.

The preview screen of the units, really hurts in the eyes. I suggest you should change it. Like this one:


The color made the abilties's description hard to read. Try changing it to a lighter color.

The fortress can be attack, while the towers guards it is invulnerable. The fountain area can be entered by the enemy, you can even get killed inside the fountain.​

The description is fine, it has a short introduction about the map. Also, it has screenshot.

The terrain is great, especially, in the base. It has wonderful variations of tiles, and well-placed doodads.​

I see a lot of potential. It would be great, if you add more heroes. Anyways, voting for awaiting update.​
