This is obvious, but it bears repeating: THIS GAME IS NOT KINGDOM RUSH.
If you want to play KR, then go and play it. TD games by design are bound to be very similar, and it's very lame to drop an obvious and unhelpful comment.
I rated the game 4/5, and here's why:
PROS
I really like stacking towers and the hero is a nice tweak too. Seeing units climb all over some giants is a major plus. The default difficulty is balanced nicely, though some difficulty options would be nice.
CONS
My biggest gripe is that the mage and archer towers are really similar. Ghosts and golems are the only reasons to choose one over the other, throwing a wrench into an otherwise balanced game--it's very annoying to have one nearly dead ghost solo a lvl 3 swordsman tower. I'm not against premium content in any way, but even after playing I'm not really sure the content is worth it--it'd be helpful to have at least one other hero to get a little more invested.
I'd really appreciate a bookmark/unbookmark all button. It'd save me the trouble of going through the entire list to mark things, checking out the store for necessary items, and then unmarking everything afterwards.
This "revive companion" glitch is really troublesome in later levels, even with the fix posted by Balance776. I end up going to other sites to play this just because of it.
I assume the orange bar influences the attack strength, depending on how full it is when activated.
But it clearly states in the tutorial that the amount of unused summoning energy is supposed to carry over. This works for the enemy, but the entire pool gets depleted whenever I summon anything. Plz fix.
Note: Area of effect spells like massive swarm and vine field don't affect the player, but Inferno will harm you if you stand inside of it.
Also, needs a friggin save button and inventory hotkey.
