Awesome drawing and an amazing idea to combine the different farm animals in one character as the "human" coat guy and each of them add another ability. Really cool what you made in one week! We had a lot of fun. The end boss suprised us the most, totally unexpected, awesome! (We managed to kick him out of the level boundaries though so we couldn't defeat him haha, with the eggs it took to long...)
If you want to keep polishing it:
What was missing the most was player feedback, so i would start to add feedback animations such as a hit or death animation, bombs indicating when the explode and the ninja indicating when they are about to throw a ninja star.
Music was too short and repetitive to be played in a loop over and over.
Really cool project, keep it up!
All the best from the Wilma & Buddy Team
