Comment Copyright DOES exist for a reason (Score 1) 494
Is Copyright out of control in this country, and frequently abused? Yes. Does it need to be toned way the hell down and reformed? Yes. Does that excuse this game? No.
Wanting to duplicate the style and basic gameplay of a game is fine. Game genres exist for a reason, and many a solid game has been made on the concept of "hey, we liked this game, but we have our own story and characters, and we're going to change gameplay elements x and y to keep it fresh". Starcraft didn't do anything especially amazing in the RTS genre, but it paired solid, well-balanced gameplay with a couple of new elements with a good story-based campaign.
Really, even a clone that doesn't really change gameplay is generally fine as long as you at least have your own story, characters, and level design. These tend to be mediocre games that few care about, but occasionally one will succeed on its story as a "meh, this is worth playing through once" kinda thing. Even if you've got nothing going for you though, your game will simply suck. It won't violate copyright.
This, however, is very much not that kind of thing. You copied the characters. You copied the exact level design. Your scoring system is identical. Your powerup works the same way, and is in the same place. You copied the gameplay down to the point that no one would know it wasn't Pacman if they didn't see the title. Well, actually, you even used "Pac" in the title, so even THAT'S not guarenteed.
That's not merely creating in a genre, nor is it even a clone. It's a flat out copy of the game. This IS exactly what copyright is meant to prevent - you profiting from someone else's exact work. Indy means nothing here. I don't care if you're 1 guy coding in his dorm room or a megacorp, you're flat out ripping off someone else's game for your own profit, and no one is going to support that.
You clearly know how to program... apply that skill to your own idea and you'll do just fine as an indy developer. You can probably even reuse a lot of that code you just wrote on a game of your own design. Alternatively, if you have no creativity, team up with someone who's great at game design and story, but fails at code, and make it a 2 man project.
