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.

I don't feel the nostalgia as strongly as some people here since I am not over 40.
Neat interactive program with some fun science-y tools
cooky
A pretty neat little game that is good to let your kids watch or play along with you. It's definitely dated though and probably won't get a lot of replay out of it, but definitely the kind of game you'd mess with back in the day. I read that the game is apparently missing some content the original release had due to an outdated technology called Hypercard, but I don't think it was much. I also found that I needed to shift my dual monitors from extended to duplicate otherwise I got a black screen. I got this game in a Myst Humble Bundle so I didn't pay the current price of $5.99 but I'd say that it's NOT worth that much. I honestly think due to it being as dated as it is that it should be less than a $1. So might want to wait till a sale or bundle if curious. 3/5 Stars
I remembered this game from when I was a kid, so I bought it. Then I realized I didn't remember this game at all. It's pretty much a hypercard stack with a bunch of random stuff to click on. We had an entire generation of free flash games since then, some of which are more interesting than this.
Great game for today's kids, as well as for nostalgic kids of the 90s like me! No plot or bad guys, but fun exploring and clicking random things. Players will find plenty to interact with, and no shortage of humor, whimsy, and fun! A true Cyan masterpiece!
GF played it for 10 minutes and got bored.
