Probably the best tower game out there right now! I'm a sucker for tower games so I was blown away when I found this one. I've racked up 1100 hours of gameplay so far and I'm still enjoying it. I would like to see some more tower defense levels added soon. The mini games are fun and the rewards are worth the effort. Great stuff! My hat goes off to the devs!

Really fun gameplay, items and cool maps. Leveling and economy could use some improvement. I never have enough steel or gold. Quick patrol gold does not seem to scale with level. Ads (are optional) only work half the time, and I use a brand new Pixel (latest model). They expect you to pay $8 every 10 days or $15 per 30 days. Idk if people are paying that, but it's not a great deal, compared to other games.

Hello! Thanks for the detailed review and the 4 stars! Your notes on steel/gold balance, Quick Patrol scaling, ad reliability on Pixel, and pricing are super helpful. We’re working on improvements. Could you email support@gamegears.online with your device/model and details so we can investigate the ads?

This is a super cute, super fun and addicting game, and I cannot recommend it enough if you are a fan of tower defense games. HOWEVER, I also cannot recommend spending any money on it until we can link our accounts!!! It's a bit disappointing that my enjoyment of the game and willingness to support the developers is hampered by concerns of losing all progress and having to start the game over from scratch if I get a new phone or something happens to my device.
