Wanted to say that Clarion is being remade in C++! The graphics and performance will be much MUCH better, using isometric tiles, but the new engine is still in its infancy. Follow the blog to keep up to date with the progress.
And since I am now a part of a company (Perpetuo Studios LLC), I'll have artists to work on it and speed things up considerably. Clarion will be our first game. Wish us luck!
