I havent played this in more than a year, is it worth picking up again?
It has great graphics and a good story, but I suggest waiting until the final release because in each incremental release the author introduces new contents also in the earlier stages of the game, so to see them you have to start again.
Since there's much grinding, from the second time you start from scratch the temptation to just play in fast forward and skipping time with the "+2" menu option is quite high, and some events may not trigger so you could be locked out from some branches.
(Besides every now and then, old saves aren't compatible with the new release. Last time it happened with v0.98, but I read on this forum that before that it happened at least other two times nonetheless the author stating that it wouldn't happen again after the first time).
Also, in current v0.99.4 there are some missing images (some configuration of Alex's avatar) that cause annoying error screens.
They were missing since a few releases, but still unfixed (at least in the release leaked here).

Plus... since two or three releases the author had the brilliant idea of tampering with the predefined Ren'Py save/load pages, so just 25 pages are shown and any save in page 26 or more is just hidden unless you use a mod...
