Unfortunately we noticed that problem before submitting but ran out of time (lol) to properly address it. We've included a rules description on the game page now; if the board isn't too small for you hopefully you can give it a shot!
Thanks! I was able to play through it and won! After a few failed attempts :D
It reminds me of board games like Carcassonne. The 8-bit rendition of Scarborough Fair made me chuckle. Some of the SFX are very loud though, and there was one that got bugged towards the end. (Might have been because three vikings were beating up a single fort.)
Overall it's charming and I liked it! It really is real-time strategy.
