Game is free. And it's fine. It's also free - but it reeeally wants your money. Your acceleration could be so much faster if you just microtransact once. Or twice. You don't have to, of course - because it's free - but think of all the fun you COULD be having if you microtransact. It hits all the major points and complexities of a good tower defense. Boards are designed to be played actively or idle. If you've played these games before, you'll enjoy it. But you'll enjoy it more and FASTER if you open your wallet.
TL;DR: Nice Idle Tower TD, ruined by not-so-micro-transactions. A game of kind "free-to-play mobile game" with "micro"-transactions. This base results in usual main features of such games: [olist] [*]Maximized addiction and fomo (fear of missing out; bonuses for being active, daily goals, events, etc.). [*]Introduction of needless limits and annoyances you shall spend money to get rid of. [*]Tournaments with pay-to-win system. [*]Overload of options, towers and upgrades. [*]Advertisements [/olist] Do yourself a favor and stay away from this kind of game.

If I'm being honest, I rather just buy bloons TD either 5 or 6 and play that instead.
This is much more an idle game than it is a tower defense game. I do have mixed feelings about the game, it's been pretty fun but more in a spreadsheet type of way than a strategy game. It doesn't scratch the same itch of other fun tower defense games (think Gemcraft, Bloons, Creeper World, etc.). Most of the game is centered around adding small boosts to your heroes so they perform better as you repeat the same map 1000s of times. I'm going to give a negative rating because this game really has too many pay2win features. If you want to play casually you can slowly unlock some of the permanent payment upgrades. Once you pay for them they are unlocked for good, like 2x experience. Essentially if you don't buy this leveling heroes (which you're going to spend months doing) will take twice as long. It almost seems like you're wasting your time if you don't drop 10 dollars on this. There are a bunch of other upgrades like that, like double battle pass experience and double battle pass rewards (really strong monthly benefits). If you enjoy the game, expect to spend somewhere in the range of $100 in order to unlock all of these things. I would only recommend this if you're okay with spending a decent chunk of money to progress. Otherwise I think you'd be much better off on spending that money on games that provide a much more fun experience while playing them.
You need to leave the game open for THOUSANDS of hours to get to the end-game, not even to 100% the game, just to reach the endgame. It's also extremely pay to win and the ads popping on your face is very annoying. The game is also just a port from a ♥♥♥♥♥♥ mobile game to PC Not worth it
Just looks like another money pit, its f2p put it locks everything behind either a crazy amount of time or money if you want reasonable progress that's not just full afk.
Not a bad tower defence idle play game however it has 1001 ways to spend money unnecessarily. Developer is too greedy so I provide a negative review.
it's like, okay i guess. their ads use AI slop tho
It is an medium game (a lot of paywalls, but can be done for free with time); however, it is starting to use more and more IA generated images.
