Colonial Space is sweet; I'm really enjoying it!
I've been playing through the #UnitSeries, and my only complaint is having to re-search for the series after I've played a level.
It's pretty easy right now, since they are all grouped together, there's only a few maps, and are on the last few pages, but once some more series come out it will be more difficult to find an entire series.
This is on my list and something I'm working on today actually...
You can try to check the 'fav' box on the maps you want to play, and then check 'favorites' as filter. (use the favorite map list as a to-play list instead of using it to list your favorite maps)
Excellent! Thanks! ;D
