Mario goes on a quest to a mysterious new land. Fun ensues, many baddies in the way. I've been working on this for a bit in my spare time.
About the hack: Mario goes on some sort of quest. Not too sure about the plot, but that's not overwhelmingly important. This is a Mario game!
As for the level design, I spend a lot of time on each level, and I don't have much time to spare. I enjoy non-linear level design in platforms, and I'd really like to capture that here. Tweaking the levels to my liking can be very difficult, sometimes I am a bit of a perfectionist. I am trying my very best to capture fun level design. I hope for a demonstration patch to be out soon (I very much would enjoy hearing community feedback).
Here's what I have right now:
Main overworld. This is mostly finished, all events are input. I like how it turned out. I made it a link because it is a large image.
Cave map. It's a watery-themed cave, as you may notice.
Random castle. This was initially planned to be the first castle, but it must be moved. I like its design much, but it is much too difficult for a world 1 castle. I'm thinking maybe world 5, but we will see.
Plains level. Probably level 2, Fog-laden path. Sprite set is likely staying, but level itself needs work. I like how the BG palette turned out here, it's supposed to be more evening-like.
World 1 with events. There are many shortcuts on the map, not only limited to the star warps
World 2 castle entrance. Tile set looks nice (I think foreground works well with background), but I may tweak block colors.
Level 1. Not much else to say here, to be honest.
Ice world map. This one came out very nice, needed many revisions to get a decent design for some reason. Submaps can be difficult to design when you have too many ideas.
There is much that I intend to implement (Sprite status bar for increased BG palette without interference, Layer 3 backgrounds, HDMA bg colors) but that is for later.
I will try to update this thread when I can. I am a bit slow, but I would appreciate any comment on my current ideas. Thank you for looking!
