Wow, this is a really great idea!  Think you are on to something here.

I did like the idea! Making a turn-based RPG under these restrictions is quite a challenge, and I think you have a great core for a game here. I was able to complete it, and even had to use a little bit of strategy on the final boss. With a few fixes (the text tends to go off-screen) and some sounds, this could be pretty good. Nice job.
