Vulnerability Fixes Fix
During the recent vulnerability fix update, we mistakenly updated to a past development version. We sincerely apologize. We have now replaced it with the latest version (as of the major update on November 3, 2021) with the fix patch applied. We deeply apologize.
We have released a patched version addressing the vulnerability in Unity-made games announced today (October 3, 2025). As a result, the Unity logo now appears during startup.

Add post-clearing features and achievements
Added timer to stage select after clearing . You will be able to check your best time for each stage. Added boss rush mode to stage select after clearing . You will be able to challenge the all boss rush with no deaths. We've added achievements related to the above two new features . You can also check the conditions from the achievements, so please challenge them!
Adding Achievements We've added a new achievement for clearing all stages. Even if you have already cleared a stage, it will be unlocked on the stage select screen. Future Plans I'm planning to add boss rush mode, time attack in stage select mode, and achievements related to these modes. I'm currently working on this.
