I think v0.5 was well worth it. and even surprised me, in length, because I remember when I first played it, there was times when I tought, okay this is where it is end, and it was still on going.
my only complaint is that save files started to messed up, so I will have to replay the whole game, and I hope saves will work for . v0.6.
Now v0.6 gonan be an intresting case, becasue they did say it's gonna be shorter, but if it is indeed shorter, yet took almost as long as v0.5, then preper for more complain.
