Marika's DokiDoki Dungeon
Read full descriptionHide full description
- One day when Marika was walking along the beach, she saw a suspicious hole in the ground. When she approached and peeked in, she was quickly sucked in. The underground was like a maze, and there were many scary monsters inside. Can Marika escape safely by using fallen magic leaves and orbs? This is an action game in a maze that changes every time. The underground extends up to 10 floors. There is a strong master monster on each floor. If you can defeat the super master monster at the bottom, you may be able to escape. It seems that the creatures on the beach are also trapped in this hole. It may be a good thing if you help them.

Verdict
The clearest difference is in-app purchases: 空の青さを知る at none against Marika's DokiDoki Dungeon's 1. 空の青さを知る also leads on ads (none vs shown). Marika's DokiDoki Dungeon's advantage is iOS requirement (13.0 vs 15.5). On price, update cadence and device support there is nothing between them.
