As I'm writing this post, only the Windows version is available. The Linux version will hopefully be up before Monday and I will have a demo up for Linux as well. I will specifically be testing Software Inc. on a machine running Ubuntu 14. I'm not sure about the Mac version yet, it will be up as soon as I have a chance to test it. Naturally, you will have access to all versions as they become available if you buy it now.
Assuming Software Inc. gets through Greenlight(Browser link here - Steam link here), you will also get a Steam key.
Pricing
The game is currently 10$ and will be throughout the pre-alpha phase.
My plans are for it to be 12$ in alpha, 14$ about half-way through the alpha, 16$ during beta and finally 18$ at release, excluding any tax that may apply to your country. These prices may change at any point.
Early access
I've chosen to do early access because I don't have a lot of money to sink in to this project. I really want it to have pretty character-models with cool animations, a pretty graphical user interface and proper quality assurance. All of these things are expensive and I'm already out around $2000. If I don't raise enough funds for these things, I will still finish Software Inc. and you will still get a playable game in the end, but it probably won't feel as nice as it could have. I won't be cutting any features that I have planned, though!
Immediate future
I'm currently working on my bachelor thesis in a group of 3, which we will be defending in the beginning of April, so development will move slowly during these next couple of months.
I expect to release a playthrough/tutorial/devlog-thing at some point in the near future, so look forward to hearing my horrible accent and squeaky voice!
Semi-distant future
Other than my thesis, I have a job, which contractually takes priority, and I expect to have a job throughout the development of Software Inc.
Seeing as though I'm only one person right now, development might move a little slow, but I'm an effective programmer and I have been able to get Software Inc. to a playable and almost feature-complete state within 6 months without any help, while taking courses and working a job. So in any case, I expect it to take around 2 years to finish from now and unless something horrible happens, I will be finishing it!
