Touhou Fangames
Genso Wanderer is extremely good if you care about roguelikes at all. Genius of Sappheiros is a lot of fun if you have patience for hard RPGs. Luna Nights is solid, and I have a lot of fondness for Scarlet Curiosity. And then Mystia's Izakaya is supposed to be really good--it certainly looks nice--but I haven't had a chance to try it yet.
Spell Bubble is good if you have a Switch. It's Bust-a-Move aka Puzzle Bobble with rhythm game elements drawing from the enormous well of Touhou fan music. I mean, not merely like Bust-a-Move, it's published by Taito. Which, in a turn of events that's kinda wild to me, means that Square fucking Enix have had their hands on Touhou.
Also probably a good time to mention that the Touhou tag on itch is pretty much all free games, though a lot of them are jam entries.
