The creator of the project suggests that the license is for edits of the emojis, rather than the projects which use the emoji. [1] As someone involved with the project, I'm not sure how this should be communicated so that this is clear[1] https://github.com/hfg-gmuend/openmoji/issues/155

Going over CC-BY-SA for those used to software licenses only: If I make a work which uses CC-BY-SA material I have to provide attribution. If I modify the emoji to suit my own purposes, I need to release these new emoji under CC-BY-SA, and attribution to the originals must be provided, they may not be kept proprietary.
Using it in a project is redistribution, modifying it is adaption.

Personally I like the license you're using.
