Ratings and reviews

***Edit 3 - Everything was restored a few days later game has no issues. Dev team seems pretty active. **Edit 2 - Wiped all progress when I was allowed back in and no way to sync with old account. **Edit - No longer playable. Telling me ive played on a newer version and to download the newer version. tried to uninstall and reinstall and still not working. Pretty good. basic, but not riddled with ads and don't feel like it's just a money grab yet

It was a great casual game until the last update. The levelling progression was reasonable, if not a little easy. Instead of just slightly scaling up levelling costs alongside the bit of new content, It became a completely overscaled grind making ftp players almost incapable of ever leveling through even mid-game. Long-time players are bailing because the latest update turned it entirely pay-to-play.

The card merge is too complex with no explanation lots of cards get wasted.. you earn lots of gold and don't use it. the diamonds to purchase packs are basically only obtainable if you buy them. very unbalanced. the recent update has made the lightning 3 star tower useless, says there is an 85% chance to arc to other targets up to 7, I'm lucky to get it to arc in a single 3 round play.. please fix it. I want this game to be a 5 star game, please earn it.
