Thank you for playing!! Yes, I agree, it's a challenge for me to figure out how to make the teammate work. As for the art and music, it was disappointing even for me. I wasn't aware how hard it is to make a game in 3 days.
That's why teaming up is so important, to split the burden and to do what you like most. For example, I love coding stuff, hate drawing and have no idea how to make music, I teamed up with a 2D artist and musician, boom, we do the most interesting part of gamedev for each of us.
