The music is good but extremely short so it gets annoying after some 30 loops (still, I see it is quite common among the jam entries, and I understand it is hard to find the time to compose a piece of music that is both long and good).
Restarting every time from the first room gets tiresome, I died a lot of times. Consider having the player respawn in the last room he reached.
Also, just moving a short distance away from where a dialogue is triggered and coming back will repeat it. You could add two lines of code to avoid repeating the dialogues too often, for example until the player dies, or until a certain time has passed.
The pixel art style works well. You doubtlessly beat me in graphics, and by far. I see you have made 9 different animations for the character and the result is very nice.
Good job.
