Very difficult. A lot of fun though. I had some trouble with the disappearing platform in level 1(never finished it) but the rest I managed. Not sure if I did them "right" or not but I got to the last flag. Really be interested to see this taken further since it had almost a mirrors edge feel and flowed really well

Haha, the platform did not disappears, it falls down (I think that the first person camera didn't allow the player to see that sometimes).
Did you check the level surroundings? There was a panel telling that Shift is to Sprint, and then if you Sprint and Jump you can get to the next platform.
In my opinion, the fun part is that there's no "right" way to complete each level, but you may improve your score by playing differently.
Thanks for the feedback! I really appreciate it!
