This is pretty faithful (and, y'know, good)! Particularly in the level design/backgrounds and enemy placement, it definitely feels like a Touhou version of the first couple of Contra stages. The gameplay is a little floaty, but solid (I still prefer this movement to those rigid arcade jumps) with all of the classic aiming options, and the sprites are great, especially that title screen art. Only complaint is the lack of music, but considering the sound effects and everything else being quality, it makes sense.
