Justin Wack and the Big Time Hack

A cozy 2D Point & Click adventure featuring multiple playable characters and plenty of silliness. Oh, and there's time travel and relationship stuff going down too. And robots – lots of robots... Do you accept responsibility for Kloot's education in the modern world? If you really want to cure that cat allergy, you're gonna have to do some serious travelling... Julia has a feeling that something ain't right... Surely there are bigger problems than a broken helmet when braving the final frontier? Should you get stuck, you can always ask Daela for a hint (it's OK - she won't tell anyone). A cosy 2D Point & Click adventure... Multiple playable characters Puzzles based in logic with a wacky edge Sleek 2D animations Fully voice acted Built-in hint system Ron Gilbert himself backed the Kickstarter :O
