Not bad..but overdone
Considering that you've used a 3D engine to make this shooter; I'd assume that you had a busy time when it comes to making it; I congratulate you for that, but when it comes to the gameplay itself; for the first moments it kinda feels mediocre, though impressed by the graphics, but the gameplay felt somewhat dull, you did put some effort on the music but it did not reach to my expectations to be honest, however I did like the patterning with the enemies; how they move about in one certain point, but its like playing an N64 game that was commercially unsuccessful; it was only a 'Quality over Quantity' kind of thing, In case if you make a sequel, I hope you'd be able to make the game more appealing in playing and following in the roots of the Touhou series, sounds good; doesn't it? ;)
