This game is about burning toys and solving riddles. How could anybody not love it? One of the toys is a nuke, so the Touhou connection is Reiuji Utsuho

Recette=Marisa and Tear=Cirno. Also, I do not ship Recette and Tear just like how I don't ship Marisa and Cirno.

This game has nothing related to Touhou in it except a horrible Scout version of Chirumiru, but that can change. Add Touhou hats to the workshop.

This game is quite fun, and rumor has it that it might have a touhou mod. If it does, I can't find it. Still worth the buy, however.

As this game features a cast where only the female characters get anything done, it's similar to Touhou. It's also fun and a good value.

There are multiple Touhou related mods for Civilization 5, including an Aya Shameimaru Civilization. Also it's a good game.

This is funny because it looks like blind, and she can taste colors. Good chance of being not American. If it is American the creator is too stuck up.

Never played this. This does have "see no" in the title, so there exists a good chance that it might include blindness. So, totally connected to Terezi.

This seems to be the only vertical danmaku on steam right now that isn't wholly mech. Also it's rather fun and features pudding. What more do you want?
