The game is really fun ! Congratulation for this work. The controls with the controller do not work properly on the WebGL build unfortunately (but it works perfectly on windows!)
I did not understand how to "ascend" in the third level though, but the idea and the graphics are very cool!
Thanks a lot for the review ! There is no way to actually fly in the game, you only have to be close to the player during the recording. That means you can wall slide, slowly going down, when the player is slowly going up. When you slide too far down you can pause the recording, get up again and resume the recording !
