It's Friday 13th, Spooktober variation, which makes it the best time to push an update for a spooky game.

Patchnotes / パッチノート:

• 日本語訳を追加しました！クレジットを除くゲーム全体の日本語訳が追加されました。翻訳ソフトを使用していますので、品質がよければお知らせください
• Player bullet impact effect improved
• Player no longer loses their weapon after continuing
• Stage 2 - increased time limit
• Stage 3 Boss - Empty space no longer deals damage during phase transitions. I hated this bug so much. It's finally fixed
  
• Performance optimizations thanks to SC Engine updates

I've also uploaded a No-Hit playthrough of the latest version, check it out if you want to be awestruck - or use it as a walkthrough if you're dumbstruck:
