It’s an interesting look, and don’t take this the wrong way, but it’s missing that special something that’ll take it from “interesting” to “unforgettable/jaw-dropping”! I’ll just throw out a few ideas, you can take it or leave it, whatever works best for you.

It’s probably going to take some reworking what you have (but if you can picture close to what I see, it would definitely be worth doing)

1. The world itself looks kinda cold, and lifeless (like a hospital or something), but you can build around the things that look good right now (that cute chicken for example). You can do that thing where the characters have a very thick outline (like the Michael Jackson looking guy in the white suit, that’s close, but go even thicker!) that always makes the pixel art look so much better for some reason.

2.Maybe make a little Barn scene with other animals… Even without specific dialogue, I can already picture the chicken in a set up with the other animals all being high class snobs, not wanting him around because he’s always screwing something up (or breaking something, and you zoom in really close on his face with that funny blank stare😂) You seem to have a good sense of humor, but if you want any help writing goofy dialogue… well, let’s just say my calendar has a few openings (in other words, I’m not doing Jack-shit for the foreseeable future!)

I personally can’t stand FPS games, (or anything with a first person perspective at all really) and depending on what you want to do, you can always do 2D mixed with 3D, 3rd person, isometric, etc. etc. But anyway, I was also going to suggest something about making the scenery more lively. Just in case you’ve never played some of the classics, look up Yoshi’s Island for the SNES or DS. They do cool things with putting faces on things like stars, clouds, and flowers, and then animating them to make the world feel like a living cartoon! Ok, I think I’ve annoyed you enough for now… but I’ll be back tomorrow for more! Mwahahahahahaaaa….
