Alex Kidd in Miracle World — About this game
Alex uses his rock-breaking punches to travel through mountains, lakes and castles and confront Janken. Blocks hide money and useful objects, but some release dangerous enemies. Shops turn collected coins into vehicles and temporary powers, while several encounters are decided by rock-paper-scissors rather than ordinary combat. Careful jumps and a little preparation matter as much as attacking.
