Island Gods was great! I am trying out a paper prototype inspired by this right now. Unfortunately hit some bugs that wouldn't let me move units anymore and it got in the way of my victory. Nonetheless, will be back to play some more.
Really glad you liked it! Do let me know if you get a paper version working, I'd love to see it.
Thanks for the report, I'll try to reproduce this bug once I have some time and see if I can fix it.
