Hmmm ok I am a little torn on this one---on the one hand you've got a wide variety of choices for characters, classes, stats, moves, etc. and impressively have them all implemented and (mostly) bug-free . . . on the other hand, the combat itself is a bit of a slog, in my experience anyway. I know this is a jam game, so of course time may not have allowed it, but maybe some different maps with pre-placed features (e.g. rocks, trees, lava pools, mud, neutral creatures, etc.) or even some squares not being available could have helped, or just anything to make your actual position on the map affect more of how you can engage with enemies (or how they can engage with you).
That being said, I still find this to be pretty fun overall, mainly for the fact that you have so many options and combinations to explore. The clearly laid out UI is nice and easy to use (though you might consider looking for a more fantasy-style/less-pixelated font for the stats' UI), so everything runs fairly smoothly once you learn how it works. I feel like if you made a version that allowed for multiple protagonists at once, this would be a great way to keep track of your "map" in a real-life D&D game with friends . . . just an idea.
Anyways, awesome work, and I hope you keep developing this!
