Changes, Updates and Free Version Added

Hello folks, I'm experimenting with the store tools, and I decided to update this asset. Added a Free version to be enjoyed by students and people experimenting with creating games and I also updated the files. 

All the Assets that were separated from the big spritesheet now are added and I also fixed some loose sprites. Furthermore, since these changes affected the files, please let me know if you have any issues with it, if you do I promise to fix it, thanks!

Regards, Caio .
