Funny that, since this game is exactly the copy of Rogue-Like, same code and everything for the most part, only difference being is the art style which doesn't look all that great and it's more or less unplayable and more broken than the current working version of Rogue Like.
Imitation can be a form of praise, however, if your copying a game word for word, code for code, and trying to make a some profit or get some money from said project, news flash!, thats infringement. Had this stayed as a mod and not been made out to be a "stand alone" then there would be no issue.
In short, I highly suspect word is gonna get to Oni in the next few days or so and he is gonna request a cease and decist. Even withsome noticable changes, there is too much copy covered from the original game that risks that.
But hey, if Ron can actual make the game work and not get Oni to fill a possible lawsuit, more power to him. Though from what I've seen and played, I'm not that impressed and have a lot of doubts on that regard.
