I'm really glad you liked the game, And yes I'll try to improve the physics in the future.
And If your asking about the art, I'm not the one who actually drew it. Most of the drawings (like 90%. I only did some simple drawings) were created by my teammate Haneen. She was the artist who drew these sprites starting from the character design to the tileset. And all of them were created during the 96 hour-period of the jam.
Thank you so much for playing the game :D
