Very simple and cute game. Here are my feedbacks:
- As you mentioned, add in audio and it will make the game feels so much better.
- Would love to be able to place change the puzzle pieces after placing one of them. Now once placed, the position is fixed.
- If you have some extra time, you can decorate your landing page so it looks more attractive and people will more likely to give it a try.
As a first time game jamer, you are doing so much better compared to a lot of people! Keep up the good work :D
