Goats vs. Nazis is still currently in production, with Jim aiming to spend a year finishing up. Although Jim is currently urging people to donate towards a 14k payout to fund his project, the game will be given away for free on the PC.
This is what Jim Welch stated in his email to myself:
"The goal is to spend one year coding, designing, composing and creating art for this game. (As a single developer).
The 14K goal may seem silly but it's the pure cost of working 50+ hrs a week on a game for a year. The game will be given away free as a download to everybody. (Backer or not.) Of course I'd like to see this do well, but I'd also like to see it become a new way for NES releases to happen (as selling roms would be a BIG no no and the audience for cartridge reproductions might be too small to fund an entire game up front.)"Goats vs. Nazis will primiarily be a top-down two player action game, which features seven levels, three difficulty levels, a NES-style chiptune soundtrack, and much more.
Jim has released a non-playable NES demo for his project, which you can view below:
