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!

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 $$.

Griiiiind! Basically it's a massive grind of a game unless you either spend money or watch endless videos, which btw, if you don't watch the videos, you'll miss out on the build of towers you want to build and some items. I mean it, it's basically 'grind, watch video, level up a bit of gear, rinse and repeat'. You can get about 4 to 5 days of fun out of it until you realise you've spent maybe an hour or so worth of adverts
