  1. [R2] SLIME-ISEKAI Memories：TenSura 5/5 · US Love it: Captivated my attention to focus on the game, the mechanic gameplay is enjoyable, the way you can utilize the characters to actually mix a great combination for stories and event is exceptional, the only problem I encounter is the random closing on the app, doesn’t take away from how great the game is, wish it could be resolve in the future.

  4. [R20] SLIME-ISEKAI Memories：TenSura 5/5 · US BEST anime adaptation game by far!: Highly recommend for anyone who’s a fan of the anime/manga That Time I Got Reincarnated as a Slime. Turn-based combat is actually strategic. The characters you deploy in combat make a HUGE difference, and different enemies provide unique puzzles to solve using different characters and different tactics with their move sets. I found it fun to revisit the origi
  5. [R1] SLIME-ISEKAI Memories：TenSura 1/5 · US The game keep closing it self out after I play for 10 minutes why does it keep doing that: It makes me not want to play the game no more
  6. [R3] SLIME-ISEKAI Memories：TenSura 3/5 · US Keeps crashing: It’s a good game, really, BUT IT WONT STOP CRASHING. I can’t do anything without the game closing itself out.
  7. [R4] SLIME-ISEKAI Memories：TenSura 2/5 · US Either give me my progress or money back: I was doing something I don’t remember what and then my progress was gone I think I was around chapter 10 I think the money I spent was $100 if I remember
  8. [R6] SLIME-ISEKAI Memories：TenSura 3/5 · US Constant Crashing: Y’all can add new stuff and try to take money but can’t fix a single crashing bug. How am I supposed to even give y’all money if I crash before I buy anything. Please do better.
  9. [R10] SLIME-ISEKAI Memories：TenSura 1/5 · US I’m 2 bad: Too hard to grind to summon Need it to be easier to be able to summon for characters
  10. [R19] SLIME-ISEKAI Memories：TenSura 1/5 · US Genetic trash: Nothing special about this gotcha. It’s just another gotcha that has a Slime skin. The fact 3/4ths of the “description” for the game is just a massive disclaimer should have tipped me off.
  11. [R9] SLIME-ISEKAI Memories：TenSura 3/5 · US Constant Crashing: This game is supposed to be compatible with my phone, but for the past two years, it’s almost unplayable. I can’t do battles anymore because the game crashing during or just before it even starts; recruiting causes an instant crash; and there are even times when the app crashes during login, I spend several minutes just trying to get to the Home Screen so I can collect my login r
  12. [R31] SLIME-ISEKAI Memories：TenSura 2/5 · US Lost EVERYTHING!: I’ve been playing this game since launch but the game has now been crashing every three fights so I deleted the game and reinstalled and lost all my progress. There needs to be a profile system for data saving and recovery instead of a vague password data transfer system.
  13. [R33] SLIME-ISEKAI Memories：TenSura 1/5 · US Wow: Amazing game I think it is Awsome except for one thing game accidentally got deleted and since I didn’t have a code written down I lost 3 years worth of work you can’t link it to anything so all that work straight down the drain
  14. [R13] SLIME-ISEKAI Memories：TenSura 2/5 · US Game is extremely buggy and a lil unbalanced: If it weren’t for the fact I love to collect collab characters I wouldn’t be playing this game, when I say I surely have crashed to a point it has reached triple digits in the span of the whole Frieren event I am not exaggerating, throughout the entire event it has crashed over everything, opening packs, npc quests, battles, literally every feature and
  15. [R38] SLIME-ISEKAI Memories：TenSura 5/5 · US Best game: It’s so good graphics good auto battle free stuff o that game is better then geometry Dash
  16. [R45] SLIME-ISEKAI Memories：TenSura 5/5 · US I like the extra story: I think that the devs put a lot of thought into making this game and because of that I think that they should get more support.
  17. [R7] SLIME-ISEKAI Memories：TenSura 2/5 · US Don’t bother: Make sure to save your data or you’ll lose everything. That’s all I have to say…
