Was just perusing demos on DLSite and saw that no one really uploaded gameplay of this version of Knuckle Pine. This is less gameplay and more edited so that it looks like a full fight without the gameplay in between. Also, the big text on the screen for winning/losing is just the reminder that this is just the demo haha.
Make sure to support Cutter and pick the game up over on DLsite! I linked it earlier but forgot that YT bonks you for that hehe
