Hello 2DTK!
I'm getting close to releasing a major update to my game that includes to conversion to using 2DTK. I have some questions I was hoping you could answer.
For reference, my app's build and install sizes:
Over the air install size = 125mb
Installed on device = 749mb
From the unity editor build log:
@1x = Textures 268.3 mb 97.3%
@2x = Textures 604.3 mb 98.8%
- Any general suggestions for Sprite Collection compression?
- When using Sprite Collections are the source assets also included in the build with the atlas0.png? (I would assume no)
- What can I do to get my texture sizes down?
As always, thanks for the support!

App store compresses apps using zip. So the overall app size = zipped file size. The textures I suspect are uncompressed, and these will zip up quite nicely. However, this means that once the app is installed and unzipped it uses up the full size.
PNG textures in tk2d will work around this issue, but at the cost of load times.
Source assets don't get included in the build unless you're referencing them somewhere, should be able to verify this in the editor build.

Thanks for the input!
So I'm getting ready to release and my ipa size right now is 107.9mb. I really want to shrink it by 8mb to get under the 100mb over-the-air size limit restriction.
I've gone through all my sprite collections and turned on Reduced 16 Bit compression, which has helped a lot but is there anything else I can do to squeeze out 8 more mb from the ipa? Good to know that the png atlas format would reduce the size at the cost of load times. Any other suggestions?
Here's a list of my most expensive assets if it helps:
32.0 mb 27.4% Assets/Sprite Collections/Island Data/atlas0.png
8.0 mb 6.8% Assets/Sprite Collections/Safari Data/Safari@1x Data/atlas0.png
8.0 mb 6.8% Assets/Sprite Collections/Neighborhood Data/Neighborhood@1x Data/atlas0.png

No idea how you can squeeze 8mb, but one thing to remember is that its 8mb compressed not uncompressed.... That will work out considerably more, based on your stats, about 6x... so you'll have to actually save 48MB...
