I really enjoy the art in this game, and while a simple prototype, it is effective in giving me a cool place to explore!
I think the "main" music is a bit grating, the loop is too small so I got sick of it pretty quickly! (Not trying to be rude, just letting you know why I didn't like it)
Are you going to be taking part in the GBjam? I bet some people would love to have you as an artist or game designer!
