- “This game is beautiful; the graphics and gameplay are out of this world.”
- “Trying to get past mission four is near impossible for me, and I had to eventually resort to looking up a gameplay guide.”
- “Only upgrades that you can get you buy with real money and you only get 4 different towers to use until you buy a bundle, and even the gameplay is choppy since the towers you get are barely just enough to survive.”
- “The retry mechanics are also frustrating as, if you make the wrong choice, you sometimes have to give up and restart an entire level as it becomes obvious your meager resources are insufficient to complete it.”

grinding

Reviews indicate a mixed experience with grinding in the game. While some players appreciate the lack of mandatory grinding and the ability to progress without spending money, others find the difficulty spikes and need for upgrades lead to a tedious and repetitive experience. Overall, the game offers fun challenges but can become frustratingly grindy without purchases or effective strategies.
- “No grinding necessary!”
- “No grinding, waiting, ads, and gacha stuff.”
- “I was able to brute force most of the levels people here are complaining were too difficult without paying (e.g. mission 12), but their point still stands that if you don't pay for better equipment/towers then the game will either be too difficult to be fun, or very grindy and trial-and-error based.”
- “Was a great game but most other tower defense games are playable without purchases; they just require a lot more grinding to get currency to beat levels. This seems to be unreasonably difficult and repetitive without buying at least one of the packs - it would seem more fair and honest to just charge a couple bucks for the game instead of leading us on with free play and then halfway through struggling we find out we need to spend money to progress.”
- “Starts off with a lot of fun and some great challenges, but after a while you'll be spending days on the same mission, which gets really tedious.”
