Saw this in an ad, and I was attracted by the aesthetic of the game play. I downloaded this on launch day, and have been playing it everyday since. First few days is good, good pacing and advancement. Then, I get stuck on stage 4-10 for two days because of the multiplying boss. Got a bit frustrated so I checked the comments, ppl r saying it’s a replica of underdark, so I tried it. I would say I notice loads of similarities, and the overall objective and mechanics is the same. But the style and some gameplay is different. I would say I prefer this, with the battle gold system. Cuz it let players adjust their strategy and style.Yes, there’s similarities, the devs might have gotten inspiration from it but not necessarily a ripoff.Back to my original purpose: is it possible to obtain more resources from idle reward? I find the gap jump at 4-10 to be too big, and cannot advance the game.Overall, this is a pretty good game.
