Thank you for the feedback! As my first RPG Maker experience, I think I really could have done a lot better on the things you pointed out. My idea with walking only was because I wanted the player to move slow as the zombie, and sometimes ideas seem better when you think of them, but don't work well when implemented.
I was deciding between trying to improving what is there post-judging or whether I should take it down entirely and remake it while keeping avoiding making the same mistakes, but I am still unsure yet.
