I wish my progress and purchases from before the big update/game change. It makes me not want to play. Energy is good, pretty sure that's different from before. One criticism I have is how it's not immediately obvious what skill each tower has when you click them. And how they attack (splash, pierce, etc). All the systems feel pretty much the same from before, the only MAJOR difference is the map. The maps, while there are more, are all much much smaller now, and feel worse than the original.

Thanks for your feedback! This game is completely new and different from my previous games, so it is not possible for any progress to carry over. There are some major changes, such as allowing more than one of each hero, and especially synergies. This adds a ton of new strategy and depth to the game. Join the Discord for some deep discussions :)

It's a fun game but F2P progress seems a bit slow. I'm willing to spend some money but I can't justify four different $18 purchases in game just so I can progress faster. That's almost $80 for in game purchases for a mobile game. If there was an option to purchase the game, for a one time fee, I would be much more interested. Subscriptions and micro transactions are the bane of mobile games.

Thanks for your feedback! I'm constantly striving to balance the f2p experience as much as possible. Everything is obtainable f2p (not locked behind a paywall), and gems are pretty generous. Keep an eye out for future updates and balance adjustments :)

I saw this game from an ad and I actually liked it. I don't normally download games I see from ads because they don't have what they advertise but this game it great. Great work!! I'm so glad you guys came out with an update!!! I've been waiting for an update to come out, thank you guys! It would be great if you guys add a sandbox mode so you can test out some of the heros without worrying about losing any progress or energy.
