I'm glad you like it so much; thank you the the generous offer.
Unfortunately I have no time for any additional work at the moment. I'm also not sure how it would look for those particular characters tbh, they are designed to be 2-directions.
In any case a pixel-artist you will hire - who may have more imagination - is free to use pixeldudesmaker's assets however they like. It's CC0 after all (as is everything I've released so far here on itch.io).
sidenote: I've been thinking about some 4-direction characters recently but I'm not to be trusted with time estimates.
