Hi i can create that script for you so it can adapt to what you are creating cause i see you are doing the game by yourself. but i need to know more about it, like if you want it for console, phone iOS /android, pc,
also Controls
gyroscope ?(move the phone controls the ship movement)
touch ? like press screen boost rockets to go up a little,
keys for movement , well etc etc ... need to know that part ,
is crash an option ?
well need to know that and il do script a demo scene and some prefabs with options so you can costumize a little for diferent ships , stuff like speed, smooth land, boost. etc
i can do that script with options similar above in 2 days for 40 usd,
send you unity package of the asset working , you check it and if you like it dont forget to leave a nice review
