CREATOR'S RECORD:


UPDATE: 9/3/2024:

  • Spider enemy in level 4 is finally fixed, now it doesn't stop midair.
  • The final screen text was changed.
  • Real Mission was delayed to November. 

UPDATE: 9/19/2024:

  • Now you can shoot upwards straightly. My composer noticed the there was a slight tilt to the  up-shot and I was surprised that nobody, even me, noticed it before. This is a change for the windows version only. I won't be updating the browser version anymore because of technical problems.
