The 3D maze is very interesting! I would have liked to see a little more variation (even something as simple as different light colours) to give me some sense of location or progression; the different floor and ceiling textures worked very well for orientation, though!
Web version mostly worked well on my machine, but the framerate really struggled when looking in certain directions on level 4 (I guess each level is larger than the last, and it renders the whole level at once?), and the jar collection sound looping over the long loading screens was a big problem.
I really like the look overall, though; more content in this style would be lovely!
