Thank you for trying my game and pointing out a problem I had overlooked—it could have caused the game to crash. I hope you try it again and share your thoughts. Once again, thank you.
Thanks for trying the game! The main goal is an arcade high-score challenge, which might not be everyone's favorite genre. Also, the game instructions are already written on the description page right below the game window. As for the thumbnail, it is a direct screenshot from the actual gameplay. Thanks for the feedback anyway!
