slopes and tanooki suit are hopefully gonna be added to the next update.
Network play and 3d world are more complicated so yeah.
yeah isnt 3d world actually 3d? you could make a style to replace it like mario 2 or hd nsmbu
have you played smm2? smm2 has a "3d" world theme but 2d with 3d looking design
ok it looks 2d but thats because of the angle, it used 3d models
i feel like 3d world in smm2 just use 3d accelration to make it look 3d
