Thank you for checking the game out and saying all that! We did do the art, and in the GDD you can see more sprites we've made for the future!
I totally agree about the secret paths and potion mechanics, I ran out of time before I could fix those systems and make it more fun. We really loved working on this so we're gonna keep at it and see if we can update it once the jam is over.
Also we played your game and were blown away. Everyone who worked on it has to be very talented because it was so fun and funny, great job!
