Answer 1

It's a pretty good map.  Unfortunately, the checkpoint coming out of the cave portion is too far to the right.  Any time I'd die there I had to manually run left after respawning to have enough room to keep right momentum during my ascent to that first turkey.  These kind of things are pretty annoying and could be identified with some more testing.

Answer 2

I likes the biosphere theme and the top section with all the glass was really cool. To be honest, I wish more of the map was like that. The underground part could have been a smaller percentage. I also think that the corner cuddle jump over the spikes was where a checkpoint should have been. Fun to grind the any%
