From the FAQ:
- What if I don’t finish? What if my game is terrible?
You might not! That’s okay. Terrible games are also completely fine! We encourage you to submit anyway. The goal is that by the end of the two week period, you will have learned a useful skill in some area of game design. Even better, you just might have a really cool prototype that people would love to play.
I recommend you still post it normally, but it is up to you.
