No more stacking!?!

What happened to the tower stacking? Now it’s almost impossible to win a round unless you spend real money to level up your towers and even if you use ones to slow the hoard down, it doesn’t slow them down like it used to. This used to be my favorite game but with it being impossible to have a real chance at winning a round anymore, I don’t even want to play it and I just got past level 200…if it’s not fixed to how it was, I’m going to be deleting the app. I’m not spending money because you want to change the game and try to force money being used over actually strategy. You’re forcing me to end my usage.

Some suggestions

- Your new horde mode suffers from being too short. Enemies walk straight line and by the time you get any fun defense up, it’s over. Either bake a time increase into manually speeding up waves alongside the score multiplier or just increase it overall

- Fusing two max level cards of any rank should never produce a wildcard of that same rank. It punishes players who commit resources to level up cards and should be a guaranteed rank up.

- All gargoyles should have an effect for how hard they are to obtain. Storm Gargoyle in particular should have pushback.

New Update Ruined Game

The new update has made the game pay to win and is unplayable. I was having a ton of fun and now it is one of the worst games I have ever played. The greed of the creators sickens me.

Update wasn’t great

The towers don’t stack like they used to anymore. Darts and aces no longer multiply when you upgrade them during a run. It’s like they downgraded towers with this upgrade. Hoard time isn’t long enough either, the new hoard layout wouldn’t be bad if you had even a little more time during the run…Not a great update.
