Don't worry about it, I couldn't finish it in time either because lack of time and C# knowledge, it was fun participating, but sometimes you just cannot make it in time, hopefully you did learn more about game development. Because that's very good as now you can make better games if you use enough time, and it's not about winning or getting popular, but its for participating and learning about game development. I hope you enjoyed this jam as your first or one of many, because I did enjoy the jam a lot because I learned a lot more about unity2d.
