Shadowland: Youkai Douchuuki

This game is terribly hard. Worst thing about it are those red demon heads flying around that pop out out of nowhere, mostly if you made good progress with one coin. They kill you instantly.

At the last stage, you need to beat it without killing enemies and avoid any money. That's how you get the good ending. Here are the time stamps for the game and all endings
