  1. [R4] Legend of Slime 1/5 · GB Too much handholding: The game practically plays itself and the tutorial seems to never end. You don't get like 3 seconds to actually play the game in the first 10 minutes. You completed a floor? Interrupted. You levelled up? Interrupted. Not to mention the constant network loading every 3 seconds in between. Abysmal UX, which is a shame because the game is really cool otherwise.
  2. [R8] Legend of Slime 4/5 · GB I like this game but it has some flaws…: I’m not rating it five stars because of the ad popups… also LoadComplete, if you see this, please, I beg on my hands and knees, can you PLEASE get rid of the random ad popups?! I don’t wanna sound aggressive but OH MY GOD! I swear those ads are so annoying! 🥲 But the cauldron addition is a good one because that means that people who don’t want to spend any
  3. [R19] Legend of Slime 5/5 · GB The game: This game is so fun u can even get a sleep mode to make free money in the game its a game were u uprade your slime and get it really strong and you can get pets slimes power and shield/swords its fun play now.
  4. [R25] Legend of Slime 4/5 · GB Pretty good game, but there's one problem...: Ads pop up every few minutes, at least it's not every second like other games. I'm happy with the gameplay, but most of the game is upgrading and summoning. Cute game though, and I must approve. Reccomended for people who love afk games.
  5. [R1] Legend of Slime 2/5 · GB ads ruin this game: Great game. it gets super addictive at some times and it’s very enjoyable but the amount of ads that pop up in a short amount of time is absurd. i beg u to shorten or remove the amount of ads
  6. [R3] Legend of Slime 3/5 · GB Too many Adds: I’ve played the game for a couple of months now, and I’ve noticed the adds seem to pop-pop up a lot quicker than they used to. The constant add breaks make the game less enjoyable and playable as you’re basically just watching adds half the time. Please slow down the adds to maybe, once ever ten minutes?
  7. [R5] Legend of Slime 4/5 · GB The random ad pop ups: The thing is that the game is amazing but the only thing that annoys me the most in this game is the random ad pop ups because I’m just summoning swords or armour and then a ad pops up so please delete that feature but overall it is a great game
  8. [R9] Legend of Slime 3/5 · GB Was enjoying but I’m soft locked with a bug: I was doing really well and getting quite far with lv 5000 stats but after reaching the point of the arena tutorial it forces me into ye screen and I cannot click anything and I can’t find a solution and I miss playing this game
  9. [R44] Legend of Slime 1/5 · GB Great game… when it doesn’t crash: Recently the game has started to crash quite a bit, no other games I have do. iPhone 16 Pro model. The devs need to look into this ASAP.
  10. [R46] Legend of Slime 2/5 · GB Mad: Deleted all my progress now I’ve gotta start from 0 and I got so far in the game and had limited time slimes too
  11. [R48] Legend of Slime 1/5 · GB GA-GA-GARBAGE: Hit with an error when opening the game that bugged my game and so I lost years of progress. Good game, until it wasn't.
  12. [R7] Legend of Slime 1/5 · GB Ads: I quit. First you beg for money now the forced ads!
  13. [R12] Legend of Slime 2/5 · GB Turned for the worse: I used to love this game and by the way, I’m a free to play player that does not spend a single penny on this game.I absolutely hate these popup ads and I would really appreciate it if it could be a optional thing if you want to watch the ad and then maybe I’ll give it 5 stars. Peace.
  14. [R50] Legend of Slime 1/5 · GB Lost Saved Data and Devs Dont Care: I have had this game for a long time. I got all my stats to around level 1800, I had 6 slimes, 3 of which were SS rated slimes. All slimes were over level 120. I updated to the game to the recent patch 3.10.0 and all save is gone. All those hours taken away by updating the game. I have done updates before and this has never happened. I havent linked my account t
  15. [R32] Legend of Slime 2/5 · GB Ads: Why do I get random adds every 10 seconds I’m in a battle get a ad it makes me leave the battle then I come back and I get nothing from the battle just might as well stop playing
  16. [R20] Legend of Slime 1/5 · GB What a sad turn of events: I’ve been playing this game for years, ever since it was launched. The recent addition of multiple adverts every 2 minutes is beyond irritating. I understand that games like this revolve around money, but this update is a joke. You’re basically forcing people to pay to go ad-free (£10 for a year or £30 forever) just to enjoy the game like it used to be. This wouldn’t be
  17. [R28] Legend of Slime 1/5 · GB why the forced ads?: I’ve been playing this game on and off for a few years now usually when i’m watching tv or on transport etc as an easy background game, but now there are forced ads every 30 seconds?? the reason this game was great was because it was optional to watch the ads unlike other annoying games that i delete after a day. if you want to make more money maybe make the packs and in-app p
