“It's fine, nothing special but good for wasting time. Art is nice too, but again, nothing too special.”
“This is a surprisingly addictive game, both on steam and on android, and being able to play with the two linked is really nice. I have been playing it for about a year now and keep finding things I haven't seen before.…”
“This game is not cookie clicker, its more of if an idle game and a roguelike had a child. This game you play ~30 mins each day, and forget about it for a weeks or 2 or maybe a month, then you come back and pick it up.…”

“I have played this game for a two years now. And I can recommend it with all of my heart, I have seen this game grow like its my son. While I do miss a few elements that added charm, I hope this game never ends.”

“What was initially an enjoyable game quickly turned into one of the sloggiest slogs I've ever experienced, even from idle games. 1) It isn't an idle game. It required constant active gameplay or you do not progress at…”
“The game is fun at first and you make good progress. Then you reach the point where you're invested and want to keep going, but your progress slows down dramatically. And even worse: the further you progress in this now…”
“Been playing this for awhile and the early game is a blast. I had been frustrated with how much none idle content there was early on but it always seemed temporary and gave you large gains when you got through those…”

“While the game does have interesting things to offer it takes soooooooooo long to get there that I recommend not even starting, there are idle games who do pacing better”

“This game is straight up just a monetisation engine. You have to actively babysit it to progress, and part of the unlocks just open up new things to buy in the microtransaction store. You can just wait and babysit your…”

“Is this game just pure vice? It is. I have played some idle games and I think this Idle Slayer is the most balanced and friendly one. It's obvious that you will have to spend tons of hours to complete it, but it doesn't feel tedious like other idle games. In fact, the key of…”
— a player, Steam review · 350 hrs played“Highly addictive idle game! This is the type of game you put in the background or close and visit weeks or months later. I love the graphics and the different worlds you can enter in the portals! The progress feels satisfying; Not too slow or not too fast either. My only…”
— a player, Steam review · 153 hrs played“This isn't an idle game, so much active play is required for any progress, and that progress only happens when you get lucky with a confluence of random buffs back to back, and praying on the random boxes. If you have an addictive personality this game is kinda dangerous with…”
