Pre-downloaded the game before it came out and was hooked for a longg time. The came really stalls out as a f2p once you unlock all the areas. The in app purchases are very apparent and almost seem necessary to progress now. Recently came back to the game after the introduction of ads. Which are much too frequent, I open, and finish my mine or dungeons, and I get an ad which makes my log in much slower than it already is. Perhaps early game is still quite enjoyable but later becomes a chore

This is a cute idle rpg that gives me a half hour of things to click on every day at work. It's fun trying to optimize the vast array of mechanics. The game is generous with progression enough with $0 and a nearly ad free experience. The ads only show up if trying to maximize the rewards for the day. Otherwise, there's no distracting banner ads or random popups (except for the in-game store ads). The ad-free version is $18 and worth it for the amount of time I get out of this.

Pretty enjoyable, lots of fun dailies to do. If you're anything like me though, be wary about how easy it is to get lured into buying the various weapons and upgrades available in the shop. The burst of progress it offers is really enjoyable, but you don't have to spend a penny to get to get the same results, you just need to wait longer/get lucky. Really enjoying the new dungeon added! I especially love the mining aspect, really fun.
