This was pretty neat, I'm not sure I've ever seen this concept done in 3D before! Some feedback-
- Was a bit hard to tell which side the visuals were on, particularly when there were a lot of overlapping elements, but I can see how it is quite a tricky problem to solve and you made a decent attempt at it!
- I got a bit frustrated when I hit the spikes in the tutorial and it made me replay it from the start hahah, but I persevered through it. :p
But overall great entry, nice job!
