The clearest difference is rating: 鍵屋 at 4.8 against 謎解き㊙母の手紙2's 2.3. 鍵屋 also leads on ratings volume (16 vs 3). 謎解き㊙母の手紙2's advantage is ads (none vs shown) and review sentiment (64% vs 35%). On price, in-app purchases and device support there is nothing between them.

鍵屋 holds the better App Store score, 4.8 against 2.3. That said, the two scores are not equally well evidenced: 鍵屋 has 16 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 64% of 謎解き㊙母の手紙2's written reviews are positive against 35% of 鍵屋's, so the app with the better star average is not the one people write more warmly about.
