ヒュプノノーツ
Read full descriptionHide full description
A roguelike RPG where all you can do is go "back" or "forward" to progress. The game is playable with just one hand. Featuring a heartwarming story that takes on the theme of life for its narrative. The game itself tends to be difficult, and it's dependent on elements of luck as well. It's almost impossible to finish the game without getting a single game over. Are you up for the challenge?
XtoBird

Verdict
The clearest difference is in-app purchases: XtoBird at none against ヒュプノノーツ's 8. XtoBird also leads on iOS requirement (11.0 vs 15.0). ヒュプノノーツ's advantage is update cadence (fortnightly vs every 4 months). On price, review sentiment, ads and device support there is nothing between them.
