The original game is called ゆうしゃの冒険EDIT+ (マリオ風ゲーム). It can be found on the japanese smilebasic wiki.(Search on google "wiki hosiken petc3gou"). I already made a mod of that game with custom music, font and skin selector, but I won't upload it because copyrights. Currently, the game is in V3 but it still has some bugs.
