User Reviews
very very fun, amazing, little ads, not p2w, and overall amazing game. however, I do think its a little rebirth heavy, and a bit repetitive at times often leading to stand stills. the art style is amazing, and the developers are amazing (i recommend their other game "necromerger" its their latest and best project") but I think this game has a little to go, but sadly I dont think it will get those finishes, since grumpy rhino has moved on. atleast we have it right now, still super fun!
Fun idle game. Unfortunately progression relies on hard to get materials, and spending them wisely. If you don't you will get to a point where you can no longer progress until you grind those hard to get materials. The green gem things are the most difficult to grind and you need a lot of them or spend money, it's possible to grind them via daily missions but it'll take awhile. Other than that it's fun, silly, and an overall great time killer. Just a little grindy at times.
So far really good! I love the art and the charm; you can tell that Grumpy Rhino put a lot of effort into this game. Somewhat similar to Fallout Shelter, but it has its own unique flair and feel to it. The game is a bit slow going, but I'm fine with that and ever time you unlock a new floor or currency or mode, it feels very rewarding. I don't like how that earning the other villains takes absolutely forever and the in-game purchases seem a bit pricy. But other than that, it's a very neat game.
A fun, creative, and well thought out game. The mechanics are clever, the conversations you can eavesdrop on are always a joy to read, the characters' designs are wonderful, and the music is stellar. I adore the pixel art choice, and I love the jokes. This game takes itself the right amount of seriously, by that I mean it does everything incredibly well while making this game playful and a joy to have. I appreciate, though it may take a while, the option to unlock characters by working hard.
