I remember seeing a more primitive editor of this game a while ago, it's good to see a modern editor for this game
If I had more time to edit old games like SMW or YI, I would definitely dive straight into it as soon as it is released.
I do remember attempting old tools over the years as I absolutely loved YI as well but the alternate means is...well, a pain. But what the heck, I will still try to give this a whirl when I get the chance after this releases. It looks good and has a ton of potential.
Well done, you've done what few have attempted, and now seem to be succeeding quite well at it~! ^.=.^
Where I am found.
