Maybe as for sponsorship you could ask newgrounds or at least put in a advertisement.
The game looks like it has potential at first sight. How ever right after i started playing even with the controls stated in the author comment i couldn't find out right away what to do.
It seemed i had to equip a sword before i could use the attack key. Also it wasn't clear which item i was selecting in the inventory.
But these are just minor issues and it's a beta.
I did feel like i was playing the same stage but with different mobs, so maybe you could add different stages each passing level.
Than on a small note i believe the level gaine medals don't work. While i was playing an error with my pc occured and i had to close all windows after which i started this game again just to find out my game wasn't saved.
Hope this is of any use to you. I would love to see a full game, if you decide to make one.
