This is rocket with pen-rendered fire which you may use for your own projects if you want to. Mrgreengoody included notes on how to change the fire within the scripts (in case you want blue fire or smaller fire for your own projects). If you have any problems with using the scripts and sprites you can always ask for help in the comments (I´ll do my best to help you).
Thanks to @mrgreengoody for the original project. All I did was changing the fire orientation, adding a rocket sprite and adding vertical movement.
