Unity 2D Sprite Splicing

Unity 2D Sprite Splicing

Hey,

I've found a tileset here that I really love and I'd like to use it on my personal hobby game. Link below:

The tilesets I have been working with prior to the above link have included their cell sizes, but for obvious reasons the above links' assets don't have set cell sizes. The cells are varying sizes, yet the 3 asset files included are rather large (683px Wide / 2048px Long) and the automatic splice tool does not do the tileset any justice.

Any advice for a Unity noob like myself?

Thanks.
