Improve rotation minigame

We've made a few adjustments based on player feedback:

First, we've fixed a bug where some of the generated rotations were unwinnable. This should no longer be an issue.

We've also simplified the rotation minigame at the earlier difficulty levels to make it less confusing for new players. However, the rotation challenge will ramp up at the higher difficulty settings to provide a greater test of your skills.

Finally, we want to express our sincere gratitude for all the feedback we've received from the community. Your input is invaluable as we continue to improve and refine the game. Please keep the feedback coming - it really does make a difference!

We hope you enjoy this latest update. Happy hacking!
