The game itself is good, you need to think how to plan the usage of certain spells against certain enemies, but one thing is unforgivable: the dumbness of the key medals. Mindless and endless grind is NOT a challenge. You gave only 25 points for beating the challenges that require the player's skills and planning, while the grind medals are worth 50 points and the final medal depends on them. For how long would I have to play it to get 10 000 kills or earn 1 000 000 gold? The cost of the current upgrade for one of the runes is now 100 000 gold and there are still some 4 more to buy. For how much? A million? All these issues completely ruin the game... it is just totally dumb.
