Game needs fixing

After purchasing packs my game doesn’t work I can’t participate in tournaments or sign in to the server getting in touch with support is impossible will change to 5 stars when my account gets fixed please help

Devs no longer care about this app

No more dev support with this app don’t waste your time downloading

Used to be really fun, but it’s dead

As the title says, this used to be an amazing successor to the original, but it’s dead now. One of the most important features of the game, tournaments, no longer runs. This prevents you from the only source of a certain upgrade material that is required for an entire upgrade tree.

If you are ok with not being able to ever upgrade some of the most important upgrades in the game then it can still be fun, but you will be severely held back.

Update needed!

Its a good game but nothing is new, same towers, same upgrades, same everything, i love this game and id appreciate it if you made it more fun with more things to do and upgrade

Lost progress

I played for a while and tryed to use the save cloud and every time I tryed it froze saying connecting to server and I realized I can’t do the tournament without it so I uninstalled it and reinstalled it to see if that would fix it and it didn’t I just ended up losing all my progress
