I can appreciate that this was ZUN's first game, developed entirely in his free time, but man this game sucks. Playing this feels like the prototype for a concept you'd make before realizing that the concept isn't fun. The Ying-yang orb probably killed me at least 5 times more than any bullets did. The game is also a bit of an eyesore, there's a copious amount of dithering on almost everything, which I suspect is from bit-crushing images with higher color depth? Either way it doesn't look good. The only saving grace of this game is having unlimited continues and no content being locked behind 1CCing it besides the ending cutscene (though why you'd want to play more of this I have no idea). If you're getting into Touhou and want to see where the series started, just play like 5 minutes of this or watch a playthrough before skipping to Story of Eastern Wonderland.
