This is a, hopefully, temporary bug...***

Cosmic Osmo was created by brothers Rand and Robyn Miller, who went
on to form the company Cyan and develop the best-selling adventure game Myst. It was published in 1989 and won the 1990 Mac User award.
Cosmic Osmo has a style of gameplay similar to Cyan's previous game, The Manhole.
There is no goal, no system of scoring points, and nothing that the
player can keep in an inventory. A player can be said to have "finished"
the game if they've explored every area and found every secret, but the
game gives no feedback to indicate whether this has happened. Although
this is unconventional, it allows finding new secrets to be a genuine
surprise, while avoiding the frustration of endlessly searching the game
for the last secret to achieve 100% completion.
In 2007, a new Cosmic Osmo game titled Cosmic Osmo's Hex Isle was released, based loosely on the original's setting but with a more traditional platform game style of gameplay.
