If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
Grab a friend and together you’ll control the two blobby aliens through the levels. Cooperate to escape from the planet you stranded on. Help each other to collect the points and reach the exit. Feel free to kill your buddy to steal his stuff, but be so kind to revive him afterwards.
