Thank you for the feedback. Yes, it's just unlocking the lightning noodle. I know that isn't super satisfying for an 'end', but I made this game solo while working a full time job so I had to cut out a lot of stuff to make it in time for the game jam.
That's a good issue to point out. I'll think of ways to solve the research button UX.
Thanks for playing! I'm glad you enjoyed it.
