Thanks! About the rotation I think it is still under 64x36. If it is over that resolution it would've been out of the screen since that is the canvas size.
About the in between pixels tbh idk how that work XD
Yea I'm not sure what a good fix for it would be but I'm pretty sure it's against the rules. You could put a pixel perfect camera on it if you are in unity but I'm not sure which engine you are using. Either way the game looks great and aside from that fully follows the jam limitations. Plus I think that is just one of several category ratings.
