I am looking to collab with anyone who can contribute. 

The game that i want to "bring back to life" is one of my previous Jams https://cgpepper.itch.io/the-fish-that-could-fly

It's about a fish that wants to fly, so it hops on clouds and does freestyle tricks

this time, i am thinking that it's a rocket that is jumping from the moon, bouncing from different planets.

I do work full time, so can only do a few hours a day. So the scope and time commitment is limited.

I develop in Unity

Boy, I looked at your game, I thought it was very beautiful and well done, I would like to be able to help but I'm short on time and I'm still an enthusiast, given the degree of your ability I don't know if I could help.
