General comments: Druid lacks compelling talents, and the tooltip seems to say that it doesn't gain base damage from intellect, which appears to make running the caster tree (with healing) not work well. Haven't played warrior as much.
Overall, eat/drink time is quite long which makes talents that reduce downtime really strong compared to talents that merely increase damage.
It would be nice to be able to set a pause time between pulls to allow abilities to come off cooldown before pulling again.
The crafting system requires too much of an investment in inventory space, and I simply don't use it. It needs to be streamlined in some way: make it class specific, give it separate inventory, do away with different tiers of materials, etc.
Mage: Conjure is extremely powerful. Once you get a decent number of talent points, run 10/10 conjure, and the rest in nuking abilities, and run drink at 99%. For damage I'm focusing on Fireblast and Bolt Mastery.
Rogue: a bit slower than priest and mage. Early I focused on the Duelist tree to try and get by with massive damage, but, as with the priest, avoiding downtime is more potent. At lvl 30 I'm running 10 CS, 1 sap, 1 in pick pocket, 5 dual wield, and the rest in agile strikes.
Sap reduces downtime by keeping you alive when you pull adds. Cheap Shot reduces incoming damage. The rest are damage filler.
Priest: Focus on the holy tree. Put enough points in healing talents so that you can grind in a zone without having to stop to eat. SW:P is a one point wonder early on, it rounds up. Later I'm planning to pick up resurrection as a one point wonder, but healing is extremely strong.
If you're having trouble, wiggle the mouse up and down. Honestly I'm not too impressed with this game. My hand is cramping from holding down the mouse. Lame.
A couple of minor points: (1) the font really degrades in some cases on low quality, and (2) it would be nice for new talents to be highlighted. I find myself having to scan the entire talent listing on the skills pane to see what new bonus I earned.
Enjoyable game, a bit easy but still fun. I played it all the way through. The upgrade system is nice but it doesn't feel very responsive. It's hard to tell how much each skillup does for you. A tooltip of some kind might be nice. Difficulty levels would be nice.
I'd consider making the lighthouses point in both directions by default and remove the upgrade. The final level light towers are a bit on the strong side. Cannon towers are also awfully strong. Base arrow towers should have a bit longer range. Their weakness should be low dps, balanced by good firing rate and cheap cost. Overall, a good, fun, simple game.
Level 25 ruined it. I could certainly bounce that ball 99 times, but doing so would be a waste of my time. Pointless, sadistic, joyless stuff. Other than that, the game has a few clever moments, but is more linear click fests than actual puzzles.
Very nice game overall. Get rid of ammo. It's just busy work for the player, doesn't add anything important. The amount of money you can save by being smart or conservative with bullets is insignificant.
Great game, 5/5
Plowing through with cleric/cleric/mage/ranger atm. Double healer + aoe is really strong. The barbarian doesn't seem that good, as others have noted, he's fragile and doesn't have enough dmg/utility to make up for it. The summoner seems weak as well, as it's bad at focus fire, and bad at aoe.
