The VG Resource

I'm an early stage sprite animator and I'm having a very hard time on trying to the tilesets for the remaining stages of freedom planet. Right now, there is only one which is dragon valley.

I tried to extract them myself, but no extractor that I've found doesn't seem to work on the games file which probably contains the stages tiles: 'Assets.dat'. Now let me get this out of the way.... I'm not requesting anyone to rip the remaining stages for me. But if your offering to do so, than I'd thank you  . What I'm asking is that does anyone know any extractors to extract the files for the tilesets for Assets.dat ? From what I learned, Umod doesn't appear to work for Freedom Planet. Please post your suggestions in this forum or contact me through email on my file page to get some answers. Thank you.

uMod doesn't work for the latest version of Freedom Planet, but it does for earlier versions.
I don't know the latest it runs on though, I just have it running for version 1.15.3 because that's the earliest version I have access aside from the to-date version.
