I installed dragonsphere yesterday to try it, but I want to uninstall it and I don't know how
Two ways: either go to the Ubuntu Software Center > Installed > Unknown and uninstall from there (will take a crapload of time to refresh though).
A better option is to open the terminal and type:
$sudo apt-get remove --purge gog-dragonsphere (without the $ in the beginning)
