Hey thanks! Glad you liked it.
Yep, I was awake and working on this for most of the 48 hours. I did all the programming myself, but I had some help with art and balancing from friends. I'm glad you liked the character art, my artist friend didn't have a lot of time to put in but it really doesn't look too bad.
We might clean up this game later and add an end goal, full animation and sprite sets, and of course music and sfx. I think it could do pretty well on mobile. Thanks for the feedback!
