You need to talk again with the same man after you pick up the ball. There's also a little easter egg for the curious people who try to go up to the sky in a certain spot. Hopefully you can play again to get the ending. Out of curiosity: did you die any time trying to cross the street?
I'm glad you liked my color palette! The music for the game was almost ready, but I didn't want to be late for the jam, I'll update it soon.
Thank you for your comment!
