The updated version includes double jumping now for a bit more reasonable difficulty (you can of course still download the original that was uploaded before the deadline). I still have a lot more tweaks to try but I have a sociology paper to write, so this will have to do until I get some more time.

IMPORTANT: While in mid-air, the direction you're looking affects your trajectory. So if you need to jump a bit further aim up, or if you're going to overshoot an island aim down. It takes a bit of getting used to, but I think (hope...) it's fairly intuitive. (in the updated version this effect is toned down a bit, but still present)

Okay, this is "Island Hopping", a first person platformer-ish thing (with islands!).

The goal is to jump from island to island getting as many points as possible without falling into the water (different islands give different points and there are also various powerups and bonuses).

The controls are simply mouse to look and space to jump (you automatically move forward in the direction the camera is looking). The islands are placed procedurally.

As time goes by your speed will increase and the islands will become further apart, higher difficulty modes accelerate this process (in addition to spawning smaller islands).

See the readme for more specific info.

UPDATE: Thanks for the feedback so far! I'm definitely going to keep working on this for a couple weeks, so I'll tweak the difficulty a bit more, allow you to turn off the music (it is pretty repetitive...), add online high scores (I almost have this working right now...) and whatever else I can.
