Fun 4/5: It was interesting trying to get the different endings. One of them required a bit of paying attention, which I always like. Pretty basic but great for what it is.
Graphics 2/5: Could definitely use some better artwork. It's very rough and ready, but it gets the job done.
Music/Sound Design 3/5: Pretty basic, does what it needs to, nothing really stands out except for the one song you're supposed to play to get the "good" (I think) ending.
Concept 4/5: Not a bad idea at all. It's awesome that you play as a bard instead of just fighting the dragon, which obviously fits the theme well. I think there are ways it could be a bit more sophisticated mechanically though, incorporating some more RPGish elements, but that's a bit much to ask for a game jam. Definitely looking forward to seeing this develop!
