Game is really, really fun. but that is a really steep asking price for permanent ad removal. There should also be a limit to how many turrets can appear in a single run. It's frustrating when you can't get your good builds going because the initial choice of turrets has been diluted because every turret piles up as you unlock them. Also kinda disappointing how sharp the difficulty spikes are that you get stuck on a stage for a week or more unless you spend.

I had high hopes as it checks all the right boxes for me: 3-5 mins rounds, a mix of Space Invaders & Missile Command, customizable towers plus skills & more. Fast forward a few hours and it shows its true P2W nature. I always spend a few bucks to remove Ads or a starter pack as I don't believe in free to play, but unfortunally GD it's disrespectful to our money to the point that the "ads free" pack is almost the price of a AAA PC game. That's greed. Nope, thanks.

A really cool and fun game with decent graphics and enemy designs. The biggest issue is the difficulty curve. I'm up to normal stage 35 now and, without spending money, it takes around 3 days to grind enough coins/components to upgrade turrets to a decent level. The RNG element when selecting turrets can be annoying as well. Also, £50 for no ads? Absolutely insane!
