I could send you the direct link via Twitter DMs (yanex_ru) or via an email (me@yanex[at]org).
You need to freely provide the download. No one is going to give you their email address to download what should be an open source project.
But I completely understand you. I hope Marta will be available for everyone quite soon (maybe at the time of 0.2).
It's the same with me. If I am using a really early stage app and actually helping with testing it the last thing I would want to do is to pretty much sign up for it with my email unless I desperately need that app.
