Yep i have to quit. Im not actually gonna stop working on the game, but this week was CRAZY and i didn't have time to finish.

Same here. And my idea was too hard for me to do on time.

I too had much more ambitious idea, so on Monday I scrapped this project and started working on another one.

I'm with you, I started with game development literally just two weeks ago, I was making progress (main game mechanic is functioning pretty well, game design is kinda fun) but the migraine I got a few days ago really slowed it down, and the day after that I had lost a lot of motivation. No way I'm finishing it by tomorrow.
There will always be a next jam.
