Hello MinionSoft,
I'm glad you contacted me.
The answer to the first question: from what I notice, I'm old enough to learn enough to be able to finish this... I love Pico-8 and Lua, and every day I try to learn new things but finishing this seems like an impossible task. Just thinking about how to fly flies already gives me a headache.
Still, it doesn't matter if I finish it or not, you are totally free to use the sound effects or whatever you want. What's more, I would love for you to do it, since one of the reasons why I have started having fun with Pico-8 is because of people like you who do incredible jobs. A big greeting
