Now i'm on wave 900+ and the only thing i have to
do is skilling damage and crit %
i hope there will be many changes , more challenge and harder playstyle
Research:
The Tier researches should explored after you loose but the basic skills shouldnt be explored. That make it harder because you can't skill bonus ressources but you can research it and skill it 2-3 waves later. But the special ressources are used in the skill bonus ressources / wave should be active while the skill is not explored. (like all other used special ressources)
You should research the basic every round new. This will be more interesting and is useful with the research skill you have.
One more problem are the attack skills on the right side the "chances".
You made it too easy(all by max lvl). Fire = 100% chance -> 50% damage from missiles over time, then you have darkness = 100%chance -> -50% hp + nature = 100% -> absorb 25% hp,
only this three skills with increasing attack damage and crit % (with crit 100%) + the attack speedskill by max lvl 20 makes it so easy. And then u have the other skills too which freeze for 100%, splash damage 100%, knock back and more. Maybe you should split the damage in physical and magic damage and split the chance % and the damage/time/spell/effect...
in more skills.
My english is not good, but i hope you can understand the most i write.
This game is too easy. I played for 2 days, 4-5 hours and i'm done with this game.
The cost balance of gems are not good. You can get too early too much bonus ressource / Wave and the resource bonus is too cheap by using ressources to lvl.
The special ressources are not usefu in this wayl because of the skills with max lvl. The more often you play you can spend it on this skills and dont need to spend ressources ingame. There will be only a few skills you need to lvl later.
The big problem is the "max" of the skills and that u can max the skills with special ressources. For the future there will be no fun.
