Don't get discouraged running out of time on the game jam - this has been a tough jam this year, and I hope you can come back to game dev with new lessons to learn from this time! You should be happy that you managed to make a game in 4 days - not that many people get to do a thing like this! I'm curious to see where you go from here - it sounds like you had a lot of very interesting ideas that you wanted to implement, just ran out of time to put them all in! Hope you enjoy the rest of your jam, and good luck!
