Err... You are aware that you have pretty much plagiarized from puppygames with the man in the corner... right?
While there are similarities I wouldn't say it is enough to be plagiarized.
*Off topic: is Riven still with puppygames? Was that even a thing or am I slightly delirious?
Nope, but he was working for them in the past indeed.
It's borderline fraudulent to use this really nice artwork to draw people into your game with the promise of quality that you obviously cannot deliver yourself.
If it indeed is straight away copied then Oasix should keep the game for himself until he can switch out the graphics for something he created himself. I don't mind copying things off the internet if it is a game that you're playing with a friend, but if you publish it on several forums you should make sure that all the art is either under a free to use license or owned by yourself.
Also, this game doesn't belong in featured games (you shouldn't create games in this section, you can create it in the showcase section and then a moderator will move it to featured if it is good enough).
