Hello Masakari, this is the developer of 'zX', a Greenlight Project entry that you upvoted some months back. I wanted to inform you that after looking at the pixel artwork of Winged Doom, I felt inspired to add a similar style of distortion to my game. The screen now has a sudden RGB/CRT simulated distortion whenever the player gets hit, and it looks wonderful, it really adds a great sense of impact. I have also included a ship rotation animation. Thank you so much for your comments, they have helped make 'zX' a better game.
Regards.
