### 4/5 — 可もなく不可もなく

*2026-04-02*

注意力を身に付ける事とバラエティ番組で観たことがキッカケ。
ヒントがありつつも、難易度設定が個人的に高くて、愉しめる感覚はない。
例えば、もう少し俯瞰して観ないとわからないよね、位なら、コツを掴みつつ、挑戦する事が出来たが、序盤から詰めていかないといけない感じが作業感に繋がった。
画像自体も身近なものではないので、とっつきにくさの方が強い。
ある程度、他で遊んでた人が継続的に、無駄の無い範囲でやりたいなら、推奨。
初心者の場合はストレスの方が多いと思う。
星4評価はウダウダ記載したがゲーム自体は悪いものでは無いという評価。
ただ、煮詰めて欲しかったねってだけ。
