User Reviews

The app delivers solid depth and enjoyable play for many, but it is overshadowed by widespread monetization concerns, long ads, and updates that nerf content. While free-to-play players can still progress, the experience is hampered by subscription changes, perceived greed, and technical issues. Overall, a divide between fans who value the core gameplay and critics who view the monetization framework as the main flaw.
Pros
  • Gameplay is surprisingly deep with strategic depth and variety.
  • The game is fun and engaging enough to keep players playing for months with daily rewards.
  • Free-to-play players can still earn rewards without heavy spending.
Cons
  • Aggressive monetization and pay-to-win design, including many subscription passes and changes around permanent upgrades.
  • Long, intrusive ads and a reward system that relies on ad viewing.
  • Updates and balance changes often nerf or devalue existing content, making players feel punished or frustrated.
  • Inconsistent ownership of upgrades across servers (permanent upgrades sometimes turning into monthly subscriptions) and a proliferation of short-term subs.
  • Bugs and stability issues with reports of unaddressed problems and limited responsiveness from developers.

I like playing after work to pass the time but it’s pretty pay to win based.

Now I never and I mean NEVER would say this without genuinely meaning it but this is the most surprisingly decent in-game ad system I’ve ever encountered in a mobile game. And this is coming from me, frontline soldier on the anti-ad war. Every single ad is optional. I’m certain if I wanted to I could just not see ads, but this is the only game I’ve ever tried (and I’ve tried so many lately as I’ve been recovering from surgery so my mobility has been limited the past couple months) where it feels genuinely worth it to click the ad button and then do something else for the next minute while leaving my phone muted and then when I pick it up again I’ve got a nice amount of rewards I can use to upgrade my stats or gear or what have you. The game is fun and it feels like I’m making good progress consistently (we will see how this holds up over an extended period ofc, as I’ve only been playing for a couple days). The idle rewards building up even while playing is ingenious. The different mini game things are cute (I particularly like the gigas battles now that I’ve got some power in my slime). I was surprised by the slime town thingy and it’s piqued my interest enough to try to save materials for it. Unlocking my dragon skill was also a fun surprise. This isn’t one of those gacha games where when you start they give you one of the current “best” characters or whatever to try and make newbies feel like they’re reaching longtime player level, but I think that’s for the best here. I only have two slimes right now and it doesn’t feel like I’m missing out. I don’t feel like I’m underpowered and I’m excited to eventually get more of them. The ONLY thing I would want to add, and this is purely a personal idea, is the ability to have your own sort of “player slime”. Maybe not one that can be used in the battles so it doesn’t overshadow the character slimes, but one that represents you and can be customized with different colors and accessories. That would be really neat but that’s again a personal preference cuz I’m a big fan of customizable characters haha. Genuinely would recommend. I hope the devs are having fun with it.
