Decent game
10/28/2025

kuboom1
This is a decent game overall, but the difficulty curve ramps up significantly as you progress. The main drawbacks are the repetitive maps and the limited methods for acquiring cards.A major point of friction is the overabundance of monster cards with no clear use; I'd prefer a higher probability of getting tower cards over monster cards. Alternatively, the ability to deploy or utilize monster cards during a level would greatly improve their value and overall gameplay.

Needs Balancing

Game is fun but needs major balancing. First and foremost is the severe lack of diamonds to be able to get more cards. It’s already hard enough to upgrade the cards I do receive, but when the percentage chance of an upgrade to a higher tier is 67% and it fails to tier up FOUR TIMES IN A ROW, something is wrong. Not to mention you don’t have control over whether the outcome is offensive or defensive.On that note: offensive cards. I got stuck at an impossible level because - again - lack of cards to be able to battle with.Finally, PvP is broken. The only thing someone has to do is put a fast group followed by a slow group and they’ll win every time; cannot begin to tell you how many times I’ve lost to a zombie then fairy combo. This is the straw that broke the camel’s back and made me delete this game.

A surprisingly good game

This game has been surprisingly well designed for the mechanics presented, the cards you can get, and an overall balance of strategy and luck. I’ve played a lot of tower defense games such as BloonsTD and I would say this is one of my friends and my favorite mobile game altogether considering it’s for free. Just to point out this isn’t a bot comment I’m also chronically online and soon to be a streamer. I highly recommend this game to everyone, it may seem it’s not that great but it is ad free so far and very interactive! \(^v^)/

Overall fun

We need some new map designs, the few that are in the game get boring after a while. We also need some modes where the rounds are extended, maybe 5-10 rounds. Three rounds just isn’t enough sometimes, you don’t have a chance to see a lot of your towers fully maxed out. I’m at 200 waves, 600+ trophies currently. I’ve bought packs and may buy more, but the probability of getting monster cards over tower cards is too high.

∙ Elemental hordes: Battle against element-specific hordes for all nine elements! ∙ Elemental tower slots: Watch out for tower slots that are reserved only for a particular element in Elemental and Rare Quests! ∙ Rewind: Get another chance after a loss! Move the remaining monsters back to the start and instantly continue the fight, keeping already placed towers deployed ∙ Various UI and visual improvements
