I've found when it comes to game jams, especially as a one-dev team, we usually end up having to cut things, so don't feel bad! My first two GMTK Game Jams I only ended up with pretty unpolished games with only one level. Even this year, I ended up with less than my original plan, but learning from my previous experiences helped me focus things down to make the experience still feel "complete". The main thing is to be proud of what you did put together! Great work friend :)
