Oh yeah, I struggle with time management as well each jam... I had some more things planned for my game but I only had 3 days to work on it. The ideas you have seem very promising, I hope you keep working on it!
For me it was a total of only 2 days on which I could really work on the game. But your game is really great for the 3 days! I will probably finish the game by the end of the year. At the moment I take part in every gamejam to get back into the gamedev stuff a little bit.
