The problem with the mobile game is, you need to get the modded levels into the "addons" folder of SRB2, and mobile phones don't let you manage your downloaded files.
Not sure if there's a file manager available for phones, but what I did is just hook up my phone to the computer, search for a folder with "Srb2" in the name, go there until I find the addon folder, and throw the .wad or .pk3 files of modded games into that folder.
Then I can perfectly activiate the files in the mobile game and play the mods.
I'm not sure what your hurdle is, but that's the challenge/ solution I went trough.
And now I'm commentating on this mod anyway, pretty cool mod.
Surprised at the amount of custom coding and items it contained. I had no idea you could do inlevel cutscenes.
That's interesting, I should study that.
But yeah, level design is a bit confusing, but neat how many original elemnts you put into this.
