I just started but how big is the game it's only 187mb ( story and action wise) and how consistent r the updates?
It's pretty packed with content. Although it can feel a bit "grindy" (if you want the
good stuff right away), the scenes/characters make up for it and the story (so far) has proven to be interesting to keep you going.
As for the progression (story/"leveling") a guide isn't 100% necessary if you're one of those exploration junkies in these type of games but certainly helps a lot if you feel like you've hit a stalemate, particularly certain outfit unlocks and the Special Events added in v0.12. You can thank
Golem98 for such a fantastic guide (linked in the 1st post)
As for the updates part, they've been highly delayed mainly due to Patreon's intervention on the project. You can check that debacle in the spoiler just below the
Yellow Text in the very first post.
Due to Patreon and all that crap, last update came on July this year (v.0.12.1). The next one is gonna be up around January but won't be v0.13, instead it's gonna go up to v0.15 as more content than previously expected has been made during these past few months and since the Doc's other project (Survivor's Guilt) had it's first release a while ago, he's been focusing on The Manor now.
However!... The Doc has mentioned that for v0.15 we'll probably need to start a new save due to some tweaking been done in the system files but he'll provide a couple of "catch-up" savefiles once the new version drops.
My advise would be to play it now so you can get familiar with the game and once v0.15 drops, start it over or use one of the "catch-up" saves and keep going, tho I'd recommend a fresh savefile to experiment all the game has to offer.
