World Of Goo is a puzzle 'em up about building bouncy structures from goo, sticky stands connecting to each other as you build up and along and under and. It gets delightful yet tricky when you're juggling different types of goo balls which build in different ways. Grab World Of Goo from the Epic Games Store by May 16th
and it'll be on your Epic account forever. You'll need to get it through the Epic Games Launcher, obviously.
