If it help with the UI issues, battle and building are the pages I found that have significant issues in operating. No change between 2560x1440 and 1920x1080. Also accidentally found another bug looking at that. If you go into the build menu mid battle it breaks the game. you lose navigation and can't leave the build page.
I'm looking forward to the additions. Don't go too hard on tweaking balancing in the mean time with other mechanics coming out. No point in fine tuning a half built engine you know. You'll just be retuning once more cogs are added. Good luck I'll be keeping an eye out. :)
