I like that idea! If I iterate on the game I may incorporate it when there are more challenges. That said, I think the current game can be "won" regardless of chance once the whole game is figured out.

Haha, I didn't realize it could be seen as a bug (one issue though is that a letter may appear under the top left UI), but yes, it's designed that way to provide a challenge while players figure out the rules of the game. Thanks for your feedback!

The game is a bit of a puzzle sandbox, there are some mechanics to figure out via experimentation. There isn't a specific end screen but players could share either screenshots or scores as a form of goal setting. Thanks for playing!
