Prototyping is something that should be done by every game developer, but isn’t always. It’s important to know if your game ideas are feasible (read fun) before setting out on the long process of development. Phil Steinmeyer is trying somet…

It’s not overly complicated, which means its not the most robust program in the world. It might, however, give you the prototyping tool you need to see if your idea works or not. It seems more suited to 2D games than 3D games; the standalone games in the Games section can give you a better idea of what others have done.

Hope that helps!

Add to that that game developers (including myself), are reluctant to even look at external ideas, for fear of some kind of ‘plagiarism’ call if it’s similar to something that the developer came up with independently.

So, it’s probably not what you want to hear, but I really can’t look at your idea and doubt others would (at least on a confidential basis) either. Your alternatives are to teach yourself enough programming to do at least a crude implementation yourself, and/or to post it publicly on a forum like indiegamer.com.

Like you, I have an interest in casual games. Got hooked on collapse a couple years back and haven’t been the same since. I constantly think about casual games and jot down ideas.

In fact, I’ve got one design doc that’s fairly detailed for a game that could be pretty fun. Unfortunately I’m not a programmer or 2D artist, so my development progress has been, well, stagnant.

Wondering if you’d like to take a look at it. Shoot me an e-mail if interested.
