The game itself is really fun, and it's a different take on TD. The only reason I gave 2 stars is the ads are SO LONG and very frequent. They are "optional," but really, you can't beat the level without watching. Some ads are 2 minutes long. If the ad is short, they double it, so you must watch 2 ads. I understand the need to make money but i am watching ads as much as i am playing. This could easily be a 4-5 ⭐️game if the ads were shorter.

If you want a game that's constantly pushing you to spend money, look no further. You start the app, "Hey, spend $5 on this super duper limited edition thing, just for you." When you're in the middle of a mission, "Hey, go spend $10 to remove ads and make the game go faster." When you finish the mission, "Hey, remember that super duper limited edition thing that popped up when you booted up the game? Well here it is again, go buy it this time." Game does it's best to annoy you into spending $$.

the game was fun for the first few levels. there are a few hard ones that just require more xp/tower unlocks. then the game just gets boring around level 10. it plays better as an idle game if there was an auto skill picker, that a player could tier up. example pick hive > lazer > human ... and it plays itself. 2x speed is locked behind 50$ one time buy or 10$ a month. ads are agregiously scammy, not required but preferred to get more loot - no ads also locked behind 50$. too much 4 mobile.
