I 100% agree with your criticism. I felt the same way after getting the game into a playable state from start to finish. But my goal wasn't exactly to be inventive with this project, it was just to create a robust product that was complete as I haven't completed a project in several years. So I used this jam to get back into the habit of completing things.
I'll polish up the issues with this project and then I'm hoping that completing this jam project will give me the motivation to keep going and complete my other projects that have stagnated.
Thanks again! The constructive criticism is extremely helpful. I can't wait to start playing everyone else's games this weekend!
