well just check out scratch (free to use) and see how limited the coding is.

yeah, scratch is pretty good for beginners and just messing around, but kinda limited in the actual coding thing. but, even with that, touhou is fairly easy to do on scratch, after you get the game mechanics done. i've seen better.
to the dev: try danmakufu, it's a lot better than scratch if you wanna make touhou style games.
