well, the one that was submitted (and available publicly) for the competition was called "witchnwiz_2021_02_22_nes_dev_v_1_0_0.nes" if that is any help.
Compo forum/thread looks like it's down for maintenance .
I'm trying to avoid the NESDev Competition build as being looked at as a "demo". It's really more of a pre-alpha (or "prototype") build and it doesn't really represent the final quality of the game.
I would much rather people just try the game on PiePacker if they are curious, as that is the full version.
The NESDev build is included with the purchase here on Itch FYI.
