When I made the game, I targeted mobile platforms, so it's good that you thought that it would be better on their. I planned on adding buttons on the keyboard for the abilities, but ran out of time.
Sorry for the crash! I don't know what happened, as I had programmed it to deselect a settlement if you clicked on it when it was already settled. Honestly, I didn't realize that I had to submit either an HTML5 or all 3 platforms, so that threw me. I had only tested on windows. I know HTML5 deploy better than linux or mac, so I went with that one, which had some of its own problems.
Thanks so much for the feedback!
