This is stage 3 of a homebrew shooting game – an erotic one at that.
Stage 3 is my favorite, because it has this awesome music and because awesome stuff happens.
– Edit –
The game development has started again! Stage 5 is now complete in easy and normal, but not in hard mode.
エロゲのくせに演出が神！ということで知る人ぞ知る、まじかるぱれっど様が開発してたD2の3面です。
マジですごいです。へたれプレーだけど。
