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.

One would think it's a fairly simple concept. Get a monster, kill and capture others, heal, collect resources, etc etc. But no, it's not simple. The UI is clunky and unless you play it full screen, panels block parts of your inventory and navigation buttons. The names for things in the crafting process don't match the actual items in the game, the actual game mechanics of what resources make what, are poorly explained or not at all. There's auto crafting, which is nice, but the game uses resources and I have no idea where they're going. I finished the game, as far as achievements go, but no idea how the game actually works. Items are being used up, and I don't know by what. Auto-healing was working fine, but now it doesn't work anymore, yet I have hundreds of thousands of all the healing items. All the monsters aren't captured because the auto healing stopped and as it's a random monster spawn in each area, there's no way to tell which ones still need to be captured and where they are located. If you like frustrating games, give it a try, maybe. If you would rather play a game where there are basic instructions and the names of items actually match the name the game uses, then give it a pass.

It's a great little game by a talented developer. My only fault with it, is the lack of information and clear instructions. For example, There is a list of monsters but, when you battle them, it's random. There is no real indicator that everything in a specific area has been collected and you're often left frustrated pressing it to re-roll a fight, till you FINALLY get the right one, you think you're missing. On death, you have to fiddle to get your caught monsters healed up and back into the fight. A simple button, on any of the myriad of screens, with a heal to 100% for x-amount of potions or cash even, would be better than having to click back and forth. These are two minor issues though that bugged me, but overall, I've enjoyed the game thus far and expect to try and boost my character's to fight the top end mobs by the end of next year.... maybe. ;) Edit - 27/10/23 - Just completed the game with 100% on all achievements. Tips - 1. Plant seeds and keep planting using skills. 2. Take time and don't rush to convert them into runes. Build a small stack. 3. When capturing enemies, make sure you have the correct "pokeball?" thing, needed to capture them. 4. Watching fights is good, but sometimes you lose. If you can, Press " i " during the fight and you can heal using Runes or small health pots. 5. Enjoy the process - it's a game - have fun.
Nice little game!
Nice game for time killing and achievement gathering.
got to 10 mil coins like 3 times and it keeps resetting my coins back to "$0" so i cant get the achievement or the last island to finished off the monster collecting
Ótimo idle para jogar e passar o tempo, possui um gerenciamento de recursos com sistema de farm, dungeons com captura de monstros. Para quem gosta do gênero recomendo muito e para quem nunca jogou não se preocupe que é bem didático.
Excelente jogo para quem gosta de idle, gerenciamento de recursos e elementos de craft! Interface e Arte muito bonitas.
De bonnes idées, une interface un peu chaotique, ça donne quelque chose de moyen mais qui penche plutôt du bon côté.
Great Idle game! Continuous progression keeps the game interesting and rewarding.
