I see, indeed one of the biggest problems in making Jam games is the scale, it's really hard putting every single idea in a short amount of time, so it can be a good idea to make a very short game but with a very well done beginning, middle and end, even if it only lasts 10 minutes total, or also having a well tought out plan B to shorten the game if there is not enough time.
But even so, your game came out pretty cool and if the final segment was completed I would not have ever tought that you had setbacks with the scale, so congrats!
