I liked the idea of the map changing every time you jump (seeing one layer at a time! It was well hard and very well made to work. Although not sure if sometimes when I jumped it didn't change the dimension/layer.
I read your description as well and completely understand you mate, I got a little bit over 1.5y old and my team member has a 1y old, so it can be very hard to find time!
Great work for what you had time to do! :) The idea itself especially is great, polishing that could actually be made into a proper platformer that I bet would be a hit!
