Best tower defense game I've ever played, with engaging gameplay and minimal forced ads.
Great graphics and fun mechanics, allowing for strategic gameplay with various upgrades.
You can progress without spending money, making it accessible for free-to-play players.

The game becomes excessively difficult after level 19, often requiring payment to advance.
There are numerous ads and a heavy emphasis on in-game purchases, which can detract from the experience.
Lack of basic controls like pause and exit, along with unclear tower mechanics, makes gameplay frustrating.

The monetization strategy of the game has received mixed reviews, with many players noting a high frequency of ads that can be intrusive and necessary for progression, especially after reaching higher levels. While some users appreciate the option to watch ads for rewards without forced interruptions, others feel that the game leans heavily towards a pay-to-win model, requiring significant ad watching or in-app purchases to advance. Overall, the balance between ad rewards and gameplay enjoyment appears to be a major point of contention among players.
- “No ads.”
- “I do find them a little pushy with the in-game purchases, keeps reminding me about the same ones over and over.”
- “Would be a good game except for a huge amount of ads you have to watch for tiny rewards - they've thoroughly messed up their tokenomics... and it is pretty impossible to get past level 40 without spending money.”
- “The problem is it's pay to win late game or watch ads until the day you die lol.”
- “Good concept for a game bogged down by needing to watch endless ads or paying hundreds of dollars of coins so you can progress.”

Gameplay is generally well-received, with many praising its balance, mechanics, and integration of RTS elements into the tower defense format. However, players express frustration over the increasing difficulty, lack of clear instructions, and excessive ads that disrupt the experience. While some find the gameplay addictive and enjoyable, others note issues with clunky mechanics and a need for a pause function to enhance playability.
- “Gameplay is perfectly balanced.”
- “Fantastic gameplay and design.”
- “Great gameplay, lots of gameplay available before anything needs to be purchased.”
- “Levels get close to impossible as you progress past 65; instructions and gameplay tips are somewhat nonexistent. Although 90% is common sense, gameplay instructions would help many others with the other 10%.”
- “The description of the tower mechanics is lacking; there is no way to see enemy details or characteristics (just an HP bar), and no way to pause.”
- “I quit from the gameplay because the game uses a playbook that tends toward exponential difficulty and forces purchases to advance.”

Players generally find the game enjoyable but criticize it for excessive grinding, especially after completing the main campaign, which can lead to monotony and frustration. While some appreciate the option to play for free and earn upgrades, many feel that the grinding required to progress becomes tedious, often pushing them towards in-game purchases or ad-watching to advance. Overall, the grinding aspect is seen as a significant downside, overshadowing the game's fun and challenging elements.
- “The second problem is that after the main campaign the game becomes an infinite and very slow grinding.”
- “Spent ages grinding to build stuff up to next levels of capacity and it made no dent whatsoever on outcome (not even close by rounds--so that's a lot of replaying the same levels over and over til brain dead unless you want to pay).”
- “Really liked it but grinding the same level constantly as the reward never increases just put me off.”
