As many of us know, Nintendo has done a good job updating Giant Bomb's 2015 GOTY with new features for game creators to add into their levels, such as checkpoints, keys and key coins, fire clown cars, more amiibo costumes and skewers. While all of these updates are welcome, are there any other updates or DLC that you would like Nintendo to still add to Super Mario Maker?
Personally, I'd like two things. One, shake the Hammer Bros to turn them into the Boomerang Bros and shake again to turn them into the Fire Bros from SMB3. Hammer Bros are already challenging enemies, but it would be cool for SMM to bring back the Boomerang and Fire Counter Parts and perhaps utilize their abilities to add something new (or make something really aggravating) into the levels and see these enemies in the different styles.
Two, at most 2 new course themes would be welcome for creators to play around with. Maybe a Desert theme would be nice (don't know about the Sun coming back). Another background to include would be what I'd like to call Above Water. Remember the Big Bertha levels from SMB3 or Yoshi's Island 4 from SMW? Those are the levels I'm thinking of where you can do traditional platforming above the water but swim on the water surface. Maybe that could be a possibility for Giant Bomb to make a level involving water somewhat. Probably add Big Bertha too by giving a Cheep Cheep a mushroom. For the record, I haven't heard anything about Nintendo saying they will or will not consider adding new course themes in the future.
