Quite good! I beat the level and it was of an appropriate difficulty. I wonder why you make Warp Zone's last challenge much more difficult than others though.
Some reminders:
1. You almost entirely avoided it, but you still have some single-tiled wall in the last area
2. All wall should be at least 5 block (4 is barely acceptable) away from edge vertically. Pretty much the entire overworld messes up with this = =
3. Gravity lines/Inversion planes should not be linked horizontally in the same room with warping, or vertically across two rooms. This is seen in "this episode of Sesame Street is brought to" and between the Red Herring and room below. I understand why you would put it in this way though.
Overall it's quite enjoyable and I look forward to seeing a level from you.
(But there're just 7 trinkets)
