About this game
Only One Tower - Idle Defense is a tower defense game where you have just one tower to protect. Choose your upgrades wisely, recruit powerful Heroes, and hold the line against endless waves of increasingly deadly enemies.
• FULLY AUTOMATED LARGE-SCALE BATTLER
Watch auto battles unfold as your heroes clash against 150+ enemies per wave. Every decision matters — a single unit swap could completely overturn your strategy.
• DEEPLY CUSTOMIZABLE TOWER
Build your tower your way. Push your damage output until you're wiping out hundreds of enemies per second, or go full tank and become truly unkillable. No two builds are the same.
• THE ANCIENTS ARE COMING
Grow strong enough, and you'll eventually draw unwanted attention. Ancient beings - some older than Time itself - will hunt you down. Slay them, and claim artifacts of terrifying power.

good game, very grindy, but it was to be expected, I do like that you can't beat it in 1 sitting, the end seems so far out of reach, and that's totally fine. I legitimately only have 1 complaint, the vibration when you long press an attribute, like when I want to double check how close it is to being maxed, I want to disable that but there's no option to do so. I did buy the no ads feature, but the ads were never forced even though they are pretty much necessary in my opinion

Given at the time of this review, the game is less than a month old, so there is plenty of time to grow. The game is literally just The Tower with retro graphics, however that is not a good thing. Both games force you to do long, boring runs just to get enough marginal resources to level up something once, and the levels never feel like they matter until you dump massive amounts into them. The ads are not mandatory and help with optional gems, but rarely ever work / pop up.

Only thing thats makes this like the Tower is that its a lone tower, with labs. The rest of the gameplay is alot different , and a much better game. You get characters that protect your. crystal, you get perma add ons, instead of a tourney it has bloodmoon a rush mode, that gives you tokens for passive upgrades. starts off slow, but once you beat the t1 wave 100 boss things pick up quite a bit. and you can unlock a attachment that makes you auto level during rounds. so yeah much more idle!
