A rather interesting game, of which there were apparently some arcade knock-offs... which didn't feature the RPG element here. The mahjongg fights are relatively well balanced, with non-boss characters only playing one hand, regardless. It's arrow keys to select, space bar to chose, and Enter to pull up your menu in the match. Helpfully, all losses of points are permanent, so it avoids some of the issues other games in the genre have regarding passing points back and forth indefinitely.
