Question for Cryswar: I have been putting together a mock-up of what I think could be a GUI for DD's combat screen. Would you be interested in a terrible depiction?
If yes, there is something further to consider. I have the habit of playing games, and thinking to myself "the controls could be better, and the gameplay..." well, you can guess. Aside from a rainbow nightmare, I can also propose my thoughts on revised gameplay. Problem is, I am not sure if they are any good, and whether a proposal to rework your ruleset would be irritating - you already spent a ton of time trying to figure out stuff.
Feel free to say no. Ultimately, my what-ifs are for my personal amusement, and the odds of actually being useful are long at best.
