first off hammer fall has no lasers so it is not a ripp off of that. Second off this is a scrolling and shooting game so it is a shootoral inspired game. and third if you don't want a game that challenges you than what is the point in playing games anyway.
I don't think he copy pasted shoot i think he actually wrote it out. But he used the shooturails and the game shoot for what they were meant for to teach people how to make this style of game.
i like that you added point scoring. rengo he meant original as in the actually orignal snake game remade or relatively close to it. to many new snake games have power ups, enemies, great graphics, skins of snakes, levels, and other stuff that you wouldn't see in the orignal snake game. this one is very close.
if you were trying to make it like the orignal game snake you should have made walls that kill you if you touch them. There is also that bug. But it isn't unique just a remake of a classic make a game that is actually your own idea.
