I like the style of this game. However the balance of this game is really poor, Actually you have very few tactics but spamming skills; There is no point to order your skill since their CD are too long to save til the right time before you are defeated.
The last Boss made me upset because he is about 50 levels stronger than the one before, yet my level stops at 20 and I can not reset my abilities to make another try. Also there are many glitches that are easy to notice e.g. if you warp to kinguard and move forward you will then get stucked and have to warp again.
I will say this is an epic game if you made the upgrade much clear and able to reset and add certain weakness to each boss so that players can beat them will own skill.
