Very fun but too many battle pass and mission reward things. The game itself is great. Levels are quick and there's tons of towers and equipment to play around with. Ads are completely optional too which is a HUGE plus. My only complaint is the part between missions; there's daily missions, weekly missions, season missions, event missions; theres a battle pass, event pass, hero pass etc. I have to navigate through 10 different menus to claim all the rewards after playing a map.

Overall it's a great game. Just on the game alone, I would rate 5 stars. I have it at 4 though since there are red blips everywhere that you can't remove after clicking on them, each one is for you to see the multiple microtransactions all across the screen instead of maybe just 1 red blip on the shop icon. Other issue which is minor, the name taken feature, so many people play games and take the good names then quit so those are forever gone.

Love the tower defense and this one is a great one. Gacha based but don't let it discourage you, there is plenty of opportunities given to get what you need. Plenty of tower types and combos you can do with them to beat the level. Ads aren't forced down your throat like other games and with an option to get rid of them forever is nice for just 7.99, much better than some COs like Habby *10$ for 30Ds rip off*
