I know that it has been quite some time since the last update on this game and I have to make an apology for that. I will be resuming the project as of now because I fear that if I neglect it like I have been doing, I'll never finish it. On the other hand, the creator of Wonderboy; Ryuichi Nishizawa and a group of people have revived the Wonderboy franchise and are releasing a game Q1 of this year.
The game is known as Monster Boy and the Cursed Kingdom. Here is a link to the video and the project homepage. Enjoy and 2016 will be an awesome year. Expect great things to happen!!
