Hey, sorry about your broken save game file. Send it to me and I'll try and fix it, or at least make a new one exactly where you were. Have other people found that to be a common occurrence? There might be a bug in there that I missed. About the shift for action, it used to be alt which was worse, because the windows key was right in between the ctrl (glide) and alt (action) keys. I thought shift was an improvement, but even that's not perfect. Next time I might go with Z and X.
I'm still looking for someone to compile it for Linux. My graphics card on my PC stopped working for some reason, so I can't run it, but the code is completely finished for linux, and I just need to have someone help me hit compile.
