Best strategy game I've found yet. No ads.

I like the game, but absolutely hate the Montura upgrade system. they built failure into it, so you waste all your blue currency just trying to upgrade the levels. not only will it fail to upgrade, but it knocks you down a level or two. so stupid. just charge a single upgrade amount, and be done with it. or switch it to the red currency since I have a lot of that.

★★★

西涼太守

the game became very very boring after stage 370 something... flying monsters bypass everything, no more strategy applicable and purely a tower upgrade game. I quit at stage 384

★★

its good but I cant ever load back in. everytime I exit the app and try to go back in.. im stuck on the main loading screen that says "remote setup" im connected to wifi and everything. only way to fix it is reinstall but then it'll just happen again.

Fun game, but if you don't pay to remove ads, you can find yourself watching ads in sets of 2, each about 60seconds long... The length of the ads is absurdly long. edit: I had started to like it again until they changed something and my hero targets the most useless target instead of the best like it used to, and I can't seem to get a freaking pickaxe despite gear that buffs the drop rate. It also feels too easy now. I don't want an easier game because you nerf the drop rates. NOT WORTH IT. 0/5!
