The sixty dollars is for early access-- you get access to each route as it comes out. 30 dollars is cheaper and is for after the game is fully released; so depending on if you want to see the rest of the game now or if you're willing to wait until it's finished, both prices are fine! 30 is cheaper though, so if you feel like 60 is too much it might be better to wait until it's come out.
Hello, sorry for replying at a 4 year post, but did you pledge and receive the "full" game in development ahead of time (idk what to put it as, but basically where the game's state was at at the kickstarter.)? Is it possible to obtain the last completed copy by pledging if you wish? or is that lost media. I'm wondering because if anyone has the pledger's full copy somewhere.
