Well here's my opinion
So I must say this game is really well done overall. I really enjoyed playing it, but the classes seem to be unequal:
- Playing as full-Strength gives good damage, but the HP given is so little that you still get killed in about 2-3 shots, 1h-ko by bosses, thus making strength build really useless and hard to play. My suggestion would be to increase hp bonus, or maybe add a defense attribute that gets boosted by strength.
- Playing as full-Agility seems to be the 'normal difficulty' mode of that game. You get Dodge rate sure, but this is almost useless as you will still get killed if you get stuck in a row of bullets. The best part with this build is the attack speed. Even with low damage, the attack speed at 1 + turret level 3 was killing every monster in the screen within 2-3 seconds. However, it doesn't seem to go under 1, so it becomes useless to put more points into agility..
- Playing as full-Wisdom makes the game really easy to finish, even when starting with any class: The MP gets high really fast so that around level 3 you're able to spam the special attack all way to the end of level. Also since the special attack is actually destroying the enemie's bullets at the same time, the wisdom build seems to be overpowered.
- Playing as Mix build is a waste. It doesn't work.
Str-Agi seems to be contradictory, as the only reason to put Agi is to get Attack Speed, but putting Strength will cancel that speed.
Str-Wis is terrible. Your bullets will not be strong enough, and you don't have enough MP to make efficent use of the special attack.
Agi-Wis is also useless because in the end you do so little amount of damage with bullets that trying to make it faster will not really help. And again, not enough MP to make good use of special attack.
I hope I helped ~

So I'll say that the best thing to improve would be to make the characters more equal:
-Strength needs to give more HP, and not cancel the Attack Speed.
-Agility needs to be able to lower Attack Speed under 1, and give a little more Dodge rate.
-Wisdom needs to be decreased. Just lower a little the Magic Regen rate and it will be fine (Just a little, not too much).
