Thanks so much for the feedback everyone! I admit the physics are very janky and poor (specially on the tubes) i spent till 10pm on the final sunday trying to fix and just had to submit as it was, great fun putting it together!

I really love the idea of a sandbox-marblegame. Unfortunatly the physics seems a bit weird. the marble got stuck or bounced really weird often times. but thats something that just needs some tweaks and adjustments ;) 

would have been interesting to further deepen the rewind-mechanic into the gameplay. for example rewind only reverses forces on the marble and you can change the track while rewinding? (physics wouldn't like that either but i'm just dreaming ^^).

I had the problem that i grabbed the remote randomly very often. maybe the remote functionality could also be mapped to the left controller?

fun sandbox to mess around in, i think the physics could use some work but otherwise neat idea. i loved the particle effects and visuals of the ball, nice touch! 

Good idea, and nice use of room data.

Congrats!

I had a difficult time with the physics of the ball. I had one instance where I was using the red tube, the ball went in the tube, then proceeded to roll back up out of the tube (I was not rewinding). Also, sometimes my hand would accidentally grab the remote when I was trying to grab an object in the world.

Other than that, I can see the potential of this project. I like the use of the spatial data, and especially the use of the secondary screen.
