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!

Game starts off well, but like most, gets you stuck behind a significant paywall. Progress is slow, and stages become hard to clear. The game needs a balance overhaul. XP in stages takes too long, so you can't level up your turrets enough to complete the level. In summary, good concept, terribly executed.

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.
