I don't see any reason to give this game bonus points for having a Nintendo trademark. So much trademark worshiping in reviews. Objectively this is just a common endless climber, rather fun at start but gets repetitive quickly Why do people give this 5 stars? Go and play the game "Going Up" by Gonzossm and you will see a climber game worth 5 stars. This one just lacks diversity of gameplay elements to come even close.
Browser games have wider opportunities then Game Boy. For instance adding public high-scores. Why was this not done? How do I interpret my score without them? If there is no ending that means that all that remains is competition between players. So many people put in work in these endless games but release with them without public highscore table - making playing them useless and reducing my score significantly.
Also I dislike that score is made by length of jumps and not actual height reached. At least height should be displayed as alternative scoring system.
