Gave it another go and was able to complete the house! 5:29 was my score! I have to say the planks leading up to the high platform above the lava was the best part of the game. That could be an interesting game all on it's own. Different planks that have different powers, interesting platform configurations and booby traps. When it said that I had to glide with the wood plank I was like...Uhh... I bet I'm gonna bug out and do it wrong and fall... But nope! I flew! How friggin cool is that? Do you mind me asking how you worked that out in VR? That mechanic worked really really well.
Wow, thank you, I'm very glad you enjoyed it and made it to the end!
The glide motion is based on constant velocity:
* horizontally move in direction of sight, i.e. camera direction, with constant speed
* vertically remove gravity and move downwards with another constant speed
I set horizontal speed 5 times greater than vertical component to create feeling of gliding in the air.
