Thanks!
I wish I was this talented to make pixel art, but it is a new resource pack that I purchased to replicate the feel of the NES era.
I do design and format my own art and include them in most of my projects but not in this one.
I am releasing another short game for a game jam very soon whereby I have created my own characters, enemies etc. It will have a very different feel to this game though, so please check it out later.
