@Ikiris - I think you're stretching. Did you not get the game on itch.io for either free or after providing a tip? I don't think they make any claim that the version on itch.io would be the final version or that tipping would entitle you to such a version. It's a bit pedantic to then pick choice words and ignore other facts to meet your end.
I personally tried the game, liked it a lot and have been waiting for an announcement on how they're going to handle a full release. Soon as that kickstarter is up I'll be laying down my money. I wish people would stop trashing developers who are actually making a very good game just because they want a solid revenue stream. We should be greatful that there has been an opportunity to play the game in such an unrestricted state for many months.
On a point of balance I'd say that those who tipped should probably receive a higher tier reward not just a copy of the game. Additional content that won't be present for the kickstarter for example. Minimal cost to the Devs but a nice gesture to those who supported them through early development.
