But I ask you to consider this: What if it's a matter of people not seeing your vision for the title? You've done more work than I could in a similar amount of time, but I can't yet envision how this game is supposed to flow. Surely it can't be nothing but square rooms and skeleton-bashing, but that's all we've seen - It's in Alpha. And to be honest, the gameplay, what little there is of it at the moment, is cookie-cutter bland. But IT'S IN ALPHA. I'm impressed that you even have animation at this point.
With that said, allow me to offer two humble suggestions:
First, don't take an axe to the Linux community because you've allowed your feelings to be hurt. There were 40-ish posts when I wrote this, and yes, several of them were mindlessly harsh. But if you're considering this to be even a representative sample of your audience, I believe you're making a mistake. And - god forbid - if these 40 people are your ENTIRE Linux market, then just quit making games now and rethink your life. You'd make more money recycling aluminum cans.
Secondly, it is entirely possible that you just might be making a bad game. I don't have reason to believe this at the moment (it's in Alpha, remember?), but to ignore the possibility is to set yourself up for massive failure. Bruised feelings notwithstanding, how much worse would it be to complete a bad title, complete with a massive financial investment, only to have it broadly ignored by gamers? And further, why would you believe the Windows and Mac markets to be more receptive? I want to see ToM turn into something awesome, but if you deal with criticism poorly from the people you're trying to market to, you are ensuring the game will arrive stillborn.
In short, I ask that you reconsider. I've purchased your titles before, and I very much enjoyed them. I hope ToM makes it, and I hope it comes to Linux as a first-class title. But you're going to have to make that happen. Please understand that (and I mean this in the benificent way), we are your potential customers. You are not doing us a favor by making a title for which you are then going to charge us regular price; you are offering us a product. Help us help you. Get yourself a nice, thick hide to wear, and try to dig out the useful nuggets from the steaming piles of crap offered in the comments (hard to do, but I'm also developing a game, and I've found it to be a necessary skill.)
Honestly, if you think the reaction here on Phoronix was mean, you should really go hang out on the World of Warcraft forums and listen to how members there rip long strips of hide of of Blizzard's developers. It comes with the territory I think, and I don't see how their devs keep from resorting to violence at times. I feel your pain. Just stick with it, and don't be afraid to shelve the game if it's not going to be fun. We'll understand. Just make sure that whatever you do, you do it for the right reasons.
