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?

Jan 2026 please consider an enhancement to allow us to craft all equipment gear rather than one type at a time going through each piece of equipment. you offer something similar to merge the artifacts. It is time-consuming to go through each equipment type to upgrade. ---- I really enjoy the game. no forced ads and they don't crowd your screen with ad pop-ups. I like the mini games on the village screen too.

I like the game. but with every update there are issues. new issue after the update yet again the Halloween update now it is not loading properly. none of the icons on the home screen come up when selected there is no real way to know what is going on in the icons or which ones they are. Seems like everytime there is an download or update there are more problems than fixes. so frustrating. also it seems like it is never done downloading. everytime I open it downloads it again.
