It's really cool to see how this has developed from some of your earlier work! I can immediately see some of the things I commented on IFDX are already implemented here, like impassable terrain and mouse over movement highlighting.
I am running into the same mouse usability issue.
I felt like I was having a harder time tracking combat here than in IFDX?
No menu/pause/abort/options menu. Not that there's anything really needed? But I felt stranded in the game when the bad mouseclick caused me to go into game instead of into the tutorial.
I got 0 story when I was playing. I don't know if I was just impatient or if the timing was off, but I always seemed to click at exactly the second that it popped up.
Some in-game UI for RPS combat would be awesome.
I'd love to crib from your work if you have this up on github, but I totally understand if you don't!
