Thank you for your feedback. I know, I planned to make a Menu interface and a simple tutorial, or just the tutorial at beginning. But I didn't have much time in this jam, I had pretty much only yesterday to polish it up so had to choose what to improve and decided to focus on algorithms. I still have to do some other animations, effects, particles maybe to improve the game feel. I'll keep working on it to further improve it, maybe once I update it you could have a try and check again.
