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.

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.

Of the three early Cyan games, this one makes the most sense. It still doesn't have a story or point though. You can see the seeds of what became Myst, and may recognize some sound effects from the later game, but there isn't a great deal here to hold your interest.

Total bullsheedo. Don't buy.
An okay puzzle game that is VERY short. It also has a nice art style but there isn't really a story.
The stuff nightmares are made of.
Not much to do here, a collection of mildly entertaining minigames and that's it. I feel like it doesn't have the same charm as Cyan's other pre-Myst games.
I'm an 80s kid, and as such, I do enjoy the occasional flashback to the era of low res low color platform and/or point and click games. This one doesn't tickle any ... well anything actually. I don't even think I'd have enjoyed this as a kid. There's just nothing interesting here. Clicked around for a few minutes, and still. Nothing. Looks more like a playground for the developers to test their skills, but I'd recommend leaving it there. Bye bye game.Fortunately this wasn't the last (nor the best) game those brothers made!
I don't *really* recommend this game, but its really neat in that early-90s-kids-game sort of way. There's not much game here - just a big sandbox with educational toys, more or less. With that said, there's lots of little educational and humorous tidbits, and its very typical for the style and for the era, so it earns a recommendation on those points.
