It seems the full game on DLSite has an extra segment (Like... 3-8 mins), after the Itch demo ends, but it also has sex scenes when you die, and a gallery of all the animations when you beat the game, though, there is a white bar censor over the Gym Monster's dong when your knocked down by it... But, I'd say it's worth it. Honestly, I wanted a bit more content, but, I would buy a Syahata's Bad Day 2, if the Author makes one, and it's priced similarly... I'd be interested in more of this storyline.
