Thanks for trying it out,
I was definitely going to add other mechanics to the game if time was on my side. I was considering mechanics such as: memory puzzles, queues and other types of puzzles.
The checkerboard background is definitely an issue, It didn't pose an issue for me as I spent a lot of time looking at it and got used to it.
This game was fun to make, and I will try to improve for future jams.
