Either you're missing Flash or I fucked up. Either way, go ahead and open the game in new window.
Originally this was a very different game. It had helicopters, espionage, party hats, and co-fucking-caine. It was inspired by one of the random ideas the co-creators thought up and put into an Idea Bucket for jammers stuck for inspiration:
"You are a velociraptor trying to sneak into a fancy dress party"
There was jumping, there was a classy raptor, there were collectibles.
And then Stencyl up and fucking killed Andrew's project, removing most of the assets in the game and then autosaving.
Undeterred, Andrew continued and salvaged what he could, creating a game that still contains a classy raptor, jumping, and... some buggy physics that must be exploited to complete the game.
Party hard, classy raptor.
