Here is list of features and hacks that are known* to be in Newer:

Dozens of custom tilesets
All new original music
All new 2D Map engine with custom maps
New enemies
New bosses
New mini-games
New sprites (blocks, controllers)
New effects... and MORE!
Also includes an old mechanic from the days of the NES!
Hacks:Music Hack - Instead of just replacing the original songs, you can have up to 100 songs without drums (IDs 100-199) and 56 songs with drums (IDs 200-255). However, these particular limits are easy to change as long as the ID stays between 0 and 255.
Tile God hack - You will be able to spawn/destroy almost any tile from any tileset being used in the Area... and on any layer as well!
Connected Pipes - will work properly
Tileset Slot Hack - Ability to use any Pa1,2,3 tileset in any Pa1,2,3 slot
Animated Tilesets - Ability to create and use animated tiles. The whole tileset can be animated.
Sprite Retexture Hack - Multiple versions/colors/textures etc of the same sprite, loaded all at once in your level. You can have a rainbow assortment of Goombas or ? Switches for example. "It's a hack that lets us use multiple textures at the same time".
Sprite Resize Hack - "We can scale up (and actually down) any enemy to any size we want."
Randomised Tiles Hack - Allows the game to randomly choose terrain tiles like it does for original tilesets.
Confirmed Sprites/Enemies:Angry Sun - Making its return is the Angry Sun from SMB3!
Re-Coloured Enemies - Blue Goombas for underground levels, Blue turtles for snow levels
Sprite 169 - Custom sprite... contains the word "magic"...
tag_thunder - Custom sprite which contains at least 7 different uses.
Custom Boss - King/Mega Fuzzy
Yellow Coin Rings - "are like the ones in Another, just re-skinned to be yellow. Collect all 30 during a coaster ride in Newer to unlock the last star coin."
Fake Star Coins - Haha, fooled you!
Tools:(To be released some time after Newer)
Reggie! v4 - an updated version of Reggie! that will have the Newer Hacks integrated.
Koopatlas - The map equivalent to Reggie!. You will be able to create brand new [2D] maps, from scratch... it doesnt edit existing 3D world maps. You can make whatever pattern you like, and the game can handle up to 42 levels a world in up to 10 worlds - but a bunch of those slots are reserved. If you stick to the slots before that (1-19) and skip a couple of the regular levels that have hardcoded behaviour you get around 187 levels. So you can have way more (or less) than retail if you so desire.
Koopuzzle - The map equivalent to Puzzle. It is used to set properties of tiles for your maps, and to create Objects for easy pasting of multiple tiles.
LayoutStudio - For working with brlan/brlyt animations. (Unfinished)
