You make this game more bad, day by day. The new challenge with random cards: No magic light, no detector an 5 of 15 waves shadow warriors. death in round 15 of 250. And that for kreds. You must be a little stupid or never play your own game.
I grinded a lot. I'm lev 52 now and all spells and towers are on max lev. But 3 exceptions: dragon tower, sun tower and lightning tower. I just cant get them. They apeared about 100 times in the available 5 card list, but i never got them. It seems the game want to force me to buy them with money. That force me to downgrade my rating. Its very frustrating to play for weeks without usefull rewards.
"That's what makes this unit hard to beat. Towers have no priority between creatures."
Oh, i know some more ways to do that. Just remove upgrades and all types of towers after wooden tower. Good sugestion, hmm?
The first game on Kong i give 5 stars after 10 minutes. I played about 1000 TD games in my life and this one is the best one till now. I wonder about the low playing rate. Perhaps it is a Kong marketing thing? This game dont appears in the start page suggestions. Why?
A small wish: dont nerv with special offers after every level. Im willing to pay a little for a good game like this, but i decide when or what. Every nerving offer reduce my drive to buy something.
last: sorry for not perfect english. I hope my writing is understandable :)
