I totally understand your point, it was kind of the same for us. We discovered the jam a week and a half after it started… but we gave it a shot anyway!
You did a great job, seriously. Don’t dwell on what you could have done, just remember that you built a whole game from scratch in a very short time, and that’s already an achievement!
I just wanted to share my experience to let you know how I felt during my playthrough, and hopefully give you a few ideas based on my background as a developer because you can definetly do a banger!
