Possibly old notes. See if newer versions fix this:
Botanicula uses Adobe Air. It can sometimes complain about missing Gnome Keyring when installing. Correct as follows:
# ln -s /usr/lib/x86_64-linux-gnu/libgnome-keyring.so.0 /usr/lib/libgnome-keyring.so.0
# ln -s /usr/lib/x86_64-linux-gnu/libgnome-keyring.so.0.2.0 /usr/lib/libgnome-keyring.so.0.2.0
Then use "Adobe Air Application Installer" to install it.
