This was something that had been at the back of my mind for quite some time (even having dreamed about working on it one time) but for whatever reason, rarely ever entertained the idea of making it. Feels a bit refreshing (and better in a way) to make a sequel to something that isn't Mario Must Die-related for once. In spite of what my opinion about making/testing exaggerated platform hell levels has been lately, I still look back very fondly on the original Hertz Donut. I think of it more as a creativity showcase that just happens to be hard as nails rather than a hard as nails hack that just happens to feature creative moments.
Difficultywise, I expect close to or slightly harder than the original Hertz Donut. Like the original, it is (intended to be) do-able without slowdown and does not utilize any advanced tricks or precise glitches (e.g. double shell-jumps, P-switch jumps, mushroom juggling, power-up recycling with Yoshi, etc.)
Since the final stage of the predecessor was called 'Omegalomaniac' I felt it logical to call the first stage 'Alpha Dog.'
The first 2 'special submap' levels:
Horizontal level wrap (that Mario himself isn't allowed to experience).
Mario is screwed.

How am I so creative? I think taking walks might have something to do with it.
Every single level I will ever make in SMM2 will be easier than Ultra Necrozma.
