5 stars: Honestly, it's a great game. I don't mind the purchases because I can understand how much time it takes to develop something even this simple. The game is a great time killer if you like watching your towers. I don't even idle it really. I open it, collect offline, clear a few waves, close it. I just got to mythic level after a few days and I'm still pretty driven to keep upgrading. It's interesting.
5 stars: Honestly honest to what it says. Idle based tower game. You can spend money to progress faster but its not needed. I enjoy the concept of the towers being different \
4 stars: Great game to kill time, take a very long time to make it to end game progress and does not require any purchases. The downside is that any progress must be made with the game active. Leaving it on and walking away is a serious battery killer, but makes an incredible amount of resources while doing so.
4 stars: Honestly if you are going to make a fun, freemium, afk styled Tower Defense game, this is how you do it. I give 4 stars as the grind and climb feel too slow. Yes watching ads and using the offerwall help with this, but I put too little effort into actually watching the game to make an impact. Furthermore, the maps get redundant quickly. Overall though solid game. Simple and effective.
5 stars: Super fun game, leveling feels good and balanced. Only thing is that I feel like the mini games timers do not continue to count down while the app is closed..not sure if that's...
