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 Sep 1 → 0.14/day in the week after.
Reviews, worldwide (the counter carries no country): 6.2/day in the week to Jul 17 → 0.14/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 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.

Reviews
While the developer has stated they only apply AI-generated graphic art for the game, AI images are known to be messy and the detailing is often just a kind of noise pattern it tries to follow, whereas it would be much more coherent if all the designs were created by hand. I bought the game and its DLC under the impression they were all hand-crafted as advertised, but that was only a half-truth in that some were drawn and the rest are generated. Needless to say, I am thoroughly disappointed by what I've found in this game and I unfortunately cannot recommend paying money to play this game or continue supporting it to others I know. Were it true to its word, this would've been a much different story.
Delete the added AI models and you get a solid recommendation. Otherwise no, cannot recommend anything the promotes stolen assets.

"AI Generated Content Disclosure" also the game itself is extremely basic if youre reading this review you are probably an autistic nerdy weeb or something, thats great! whats not great is the fact that the mechanics of this game are extremely surface level, all of it is just click or click and drag. so that for the price is pretty insane in case you are not a nerd then this game might be alright but again, generative ai... PS: OH ALSO its pretty damn buggy, esp considering how simple a game like this wouldnt be very hard to develop, but the 'bugs to effort' ratio is always way too high in AI games
As others have said, AI generation being used in this sucks and the fact they keep on using it makes it even worse.
great game, unfortunately the dev only stated later on that the designs are made with AI, so i can't recommend it
Don't recommend for the repetitive gameplay Don't recommend for AI art Don't recommend for developer accepting and adding more AI Gameplay is very basic: click and drag, click and drag for every model. The only difference between each model is the art itself. If you can call AI models art. I sadly bought it and played it before I knew it contained AI back when it was brought up from "community members gave AI". I brushed it off, because maybe the game was too far into development, was already released, or some situation that they couldn't take them out now for reasons. However, there's been more AI models accepted and put it the game....... As someone who is making a game of an art form, you'd think they would care more about the art itself.
My friend bough this as a thoughtful birthday gift for me and I was enjoying until I got a few kits way through the game and decided to check the store page. "AI generated content" Immediately dropping this game because AI does not belong in gaming and I would love made by Human content.
AI? Bye!
The game is pretty solid but the dev using AI for the designs, few of which are actually original in nature, is pretty bad.
this game and dlc was gifted to me, unfortunately ai slop designs in the dlc
