Hard to start the game, i don't know why.
The grapplehook feeling is insane. I'm bad because this movement is really good but ... nothing to do with it. Perhaps you can just add an object to get at the top of the structure ... i want a goal !

The game is hard to start because I selected opengl 3.0 without knowing about the issues it causes in the browser. I have a fixed version but uploading new files to the jam entry is not permitted.
As for the goal. I had a really cool idea for this game but I didn't get around to it. I wanted to 3D model a castle before the jam which I could use as the level (since importing art is not counted towards the 3 hours). The Idea was that the player goes around collecting 'magic orbs' that make the castle slowly emerge out of the ground, revealing new paths and area's everytime the castle rises. Ultimately a 'treasure' is revealed in the deepest point of the castle.
This would've been achievable if I was more familiar with the engine and I had time to make the castle 3D model. Lemme know what ya think.
