Hey and welcome. No worries this is my first jam too. But just stay consistent and you will make it through. No idea is stupid do this for you first. Good luck.
Thank you guys for all the comments! I think i'm doing a great job on the game because i have already finished the main menu, something i think would take me three days to make, i learned a lot too!
Also first Gamejam ever, started this whole gamedev journey like 3 weeks ago and needed something to motivate me to finally start a real project. So far it is kinda working :)
