Hi! Thanks for reporting this and for the detailed feedback 🙌
About the ball puzzle — there is actually no bug there. You just need to press the puzzle start button. As shown in the screenshots, the puzzle does not activate automatically. Once you start it, you can interact with the puzzle and continue playing normally. The ball does not need to be placed manually.
Regarding the game crash after picking up the petrol oil: the game has been tested many times, and no other players have reported this issue so far. It may be a system-specific problem, but we will still look into it and investigate further just in case.
Thanks again for taking the time to share your experience — it really helps us improve the game. If you notice anything else, feel free to let us know 👍
