careful when you skip the opening cut scene -- i double clicked and it cleared my data :( DEV: perhaps put a confirmation in the center of your screen to account for accidental clicks?
prices scale very wildly in the store for items, which leads to crafting being the only viable way to get new equipment. equipment gets outdated faster than you can get new stuff, and it takes forever to increase levels. it's a grind-fest, and even though the game play is fun, its not worth the excessive time it takes to move on in levels and equiptment. 1/5 until the purchasing systems get rebalanced
Very laggy (even at low res and no particles, etc) --needs to be fixed. The "win XXX matches in a row" challenges don't seem to ever be awarded, and the EXP gain doesn't scale well. it would be a 5/5 game if these things were fixed, but until then 2/5 for a great game that's nearly unplayable due to lag.
simple, fun game. too easy though. instead of automatic locking, you should implement a user initiated lock. then its not just "move the nodes back and forth until it locks into place"
as taised said, blast wave is the upgraded heavy gun (2nd track upgrades according to the encyclopedia). however, the heavy gun is amazing when used with other guns. Personally, I used thunder/saw/heavy/saw/thunder on both sides, and had no issues through the entire game. before I had 5 tiers, I stuck to saw and thunder (thunder for air and soldiers, saw for tank and other high health stuff)
Best tactic for the final battle: use shark, spam freeze and tidal wave whenever they are ready (you'll never run out of mana). use elephants, balista, horses, archers, and warriors (in whatever amounts feel right at the time). upgrade those things as you can, but start with fully upgraded elephants and balista RoF. don't bother with the turrets, alexander never gets close enough to deal damage.
beware of exiting without saving! contrary to what you might think, you will lose some triggers that you might have activated, without them spawning again. EXAMPLE: if you solve a riddle, then exit without saving, you can't get the 4 riddle badge. the riddler says you have answered already, but the save file doesn't remember that you have.
My strategy for the sun emperor level: Use the priestess (since it's the weakest of the special units), and the hat that suppresses the spirits to one per priestess. Than only hurt the cat with the scarabs. (Pro Tip: You can still get gold scarab even if the Cat God doesn't die!)
balance recommendation for gold scarab on Sun Emperor level: Perhaps give coin bonus for killing the cat in faster? then you don't need to sit there avoiding the kill.
