I think I played this game more than a year.
Based on it I have some suggestions for the betterment of this beautiful game.

What I have seen from the begging of my game journey with this game Simple Rockets 2 to Juno New origins is that New players get bored quickly, due to building everything on their own, even designing the simple rocket gets hours ,I'm an old player I can go with it, I mean, it takes me 2 - 3 days to build a beautiful craft, imagine the pain faced by new players,

To overcome these issues and attracting more people ,Dev should add many pre - made parts like

1. Various types of plane's cockpit with simple interior designs. ( not talking about that canopy cockpit already in game)
   ( Maybe sci fi designs )

2. (a) One customizable Fuselage with different types of simple interior designs and windows ( so that players can jump in game and build and fly their flying thing quickly without taking days )

(b) adding various Rocket capsules with windows and Simple interior designs ,( sizes and colors customizable)

Let the remaining other parts for hardcore gamers to build their own fantasy crafts, gigantic planes, ships rockets etc wat ever they want.

1. Add A few simple Blueprints I'm vehicle assembly building for something to start with for new players who just downloaded this game.

2. Better UI design for Vehicle assembly building. ( right now you have to open MOVE PART TOOL. group for coloring, Part shape tool, rotate part tool translate part tool, move part tool, and part connection tool each at one time. Which is very time consuming . It can be added to the different part of the Vehicle Assembly building to make it is more easy and user friendly.

Lastly i wanna say that this game is fabulous and beautiful but it takes hours to get something ready to play in it. Which can be fixed by few Updates

Hope this message Reach out to the Devs

Thank you.
