Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0/day in the week to Aug 11 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

[h1]Pokemon Meets Forager Meets Idler![/h1] [i]Idle Monsters RPG[/i] is an idle monster collectathon game, mostly [i]Pokemon[/i] with a dash of [i]Forager.[/i] Just like the Pokemon franchise, you select one of three monsters as your starting fighter. And, similar to Pokemon, if you defeat a monster with a box corresponding to its rarity (common, rare, epic, legendary), you capture it and can use it as a fighter. Your starter monster will "evolve" as it levels up. Mine carried me through about half the game, then, when I felt stuck, I decided to switch to one of my captured legendaries and that carried me through the rest of the game. Finding monsters to fight is an annoying random roll in dungeons with multiple monsters, making it a pain at times to capture that one last monster. One small mercy here is that, once you defeat a monster and reload the screen, it becomes available to fight again without the roll. That allows you to capture a monster you defeated but didn't have the box for, or to choose a monster to grind on for levels or essence. Monsters are of four elements: Fire, Water, Plant, and Earth. Monsters have two attacks: a basic attack and one powered by their elemental essence. Alas, both are generic. No Stun attacks or debuffs or any variation whatsoever. I haven't even noticed any rock-paper-scissors elemental strength/weaknesses. The elemental essence attacks are powered only by a consumable elemental rune that you craft and feral monsters don't carry, but they do carry elemental essences with which to craft said runes. You'll still have to craft the runes to progress in the game, as they are needed to open up the rest of the land. Healing in this game is accomplished through either a simple potion or lotus flowers. The flowers allow auto-recovery in battle, and can also be used in inventory. But they must be of the same element as your fighter. Auto-recovery seems tied to max HP, but manual use of them stays at the same base limit. At first, you have to buy seeds in a market and plots in the farm and manually plant them. You'll soon be able to afford an automation to plant seeds in your inventory. Lotus flowers have three tiers. You have to manually combine a bunch of flowers to make the next tier. The tooltip fails to mention the coin cost. But, gather enough and you can buy an automation for that higher tier that doesn't seem to drain coins. You start with one small piece of land. Purchasing nearby islands, a la [i]Forager,[/i] takes various resources. Early islands have some resource buildings and crafting stations as well as places to fight and level up. First there's wood, then a mountain with both stone and iron. Mining stone also is the only way to find Rune Essence. This and the elemental essence drops off monsters are combined to make the runes for your elemental attacks. A later mountain has gold. You will need both raw gold and coins. Coins aren't dropped by monsters, but are gained through selling items as well as through minting them. Minting coins takes the intermediate step of smelting bars. All resources can be automated. The max automation is bought in town, and can be racheted down at the resource site if needed, which comes most useful if trying to mint coins. Resource management is a bit of a pain because most resources have storage limits, which, of course, can be upgraded, and will indeed need expanding to reach the rest of the land. Coin storage is one of those limits, and looks very grindy to reach the final limit, BUT I found that selling the higher tier of flowers from inventory ignores this limit. Maybe the limit is just for minting. This is a decent combination of idle game and RPG, with the RPG grind eased much by the idle part. A great QoL feature here is the ability to minimize the fight window to a small window on the world map, allowing you to do other things in the game. The quest sequence here just prompts you along the game. But the window hangs out in a corner of the world map and at times blocks one portion of the map. This is a decent early game by its developer and worth a look. I grabbed this game as part of a cheap bundle on sale, all games related to the dev. From the list, it seems the dev has gone from solo dev to working with a few friends and is making even bigger and better idle games.

It's a pretty good idle game. I bought it cheaply, so it's definitely worth it for me.
Very lack luster, clear signs of little care to design and detail. Overly complicated for very little gain. It's a Factorio of Idle Games. I'm sure it's great when you get going but I don't want to spend hours simply understanding what to do. Especially for an idle game.
tl;dr; underwhelming at best right now Pros: - it's pretty novel concepts wise Cons: - UI is very poor - the Pokemon-like aspect of it / monster collection part is very underwhelming - gameplay loops are inferior to modern idle game standards - the farming part: it works but it feels extremly bad - your typical chromium based games nonsense reusing the same 10 years old JS (probable jquery xd)
Игра очень сырая, неприятная в управлении, продержался 5 минут
So there's 2 gameplay loops in here. The first is collecting monsters, the second is unlocking new islands. Monsters are actually useless in this game. You don't need them at all. Unlocking an island requires resources that are simply clickable and later automatable. If you want to collect the monsters, go ahead, level one up and catch them all. But really, there is no use for them at all. They don't even look pretty. They have 2 stats, attack and health. That's it, that's your monster. Oh right, there's speed, which is the same for every monster. As long as monsters don't have any use besides getting more monsters, there's little to no reason to actually play or idle this game.
Не рекомендую. В игре почти нет контента. Я бы назвал это очень ранней альфа-версией игры.
There are better games than this one. No offline progress No prestige mechanic Very little depth to the game.
Další triviální idle hra, kde stačí pár kliků a člověk má rázem 100%, aniž by musel zdlouhavě přemýšlet nebo se namáhat k nějakým extra výkonům (což je relativně škoda) - beru v potaz, že se jedná o předběžný přístup
I started playing this game and there were some game breaking bugs. I mentioned the bugs and they were fixed. At this point I am not running into any additional huge issues, though there are still bugs. There are also some huge quality of life improvements that could be made here that make this a "meh" for me. I am leaving the review as positive because the devs are responsvie even 6 months after release and I do still enjoy the game.
