working on the visuals (Hoot sprites by the incredible @izzi8bit.bsky.social ) upon starting a run, there's a ~25% chance of him appearing, landing on the progress board at night; he won't leave during the day, instead sleeping through it he's only here to hang out, so he doesn't do anything else

That's on Redigit way back when he created SMBX! I think they're exclamation blocks nowadays, but they used to look this way.

A concept from SMBX I've always liked. Line guides and solid sprites are two challenges for sure, but I've always wanted to make these happen in #smw! #romhacking

If you look closely, the Renzors' positions have a one frame delay related to the platform. It'll happen as well when Mario steps on it. If this issue bothers you and you've already grabbed the sprites, redownload - it was a little annoying but I just fixed those.

They're almost wrapped up for release! I was just figuring out a way to add a setting to easily turn them into actual bosses while still letting them be enemies. Setting a digit in the extra byte of any of the platforms should now enable level end trigger! #smw #romhacking
