There's a couple things I chose not to mention here, like the new multi-targeting homing attack and the homing kick. I don't think they are significant enough to have much impact.
There's also the item inventory, which is ripped straight from Mario as well. But again, barely contributes to anything.
Speaking of Mario, the music in this game is quite good, but undeniably trying to copy the Mario feel. And it succeeds so well that it even has the same kind of jazzy sound we hear in Mario 3D World. Which would not have been intentional, as that came out around the same time as this. Sonic Team was just so in tune with Mario that they did the same thing as actual Mario. Now if only they could do that with Sonic.
I was initially planning to talk about the 3DS Lost World in this video. But this ended up being so long that it'll have to get its own video instead.
If you did want to play Lost World, for whatever reason, I do have some recommended mods in my spreadsheet. So maybe give that a look.
