Thanks for the feedback!
You are right there isn't much there yet, I wasn't even sure if I should submit something right now or wait for next Demo Day. It just ends at the first enemy encounter. There is an inventory menu on the bottom left that you can cycle through clicking the arrows on the screen currently, which I plan to expand to have more interaction with picked up items. As for the the music I added it last minute as I thought it would be better to have something than nothing and it isn't definite, I might come back to your offer though!
