It is the same base body for all so yeah, it's more about amking the creation process easier than anything else.
Originally it's in english.
It's not in the main page anymore, you'd have to dig older posts, here: https://vosmug2.wordpress.com/2018/01/12/693/
But those old demos are not representative of the final game, that's why I don't have them available anymore, it'd be better to look it up on youtube and seee if you like it by watching videos.
Also, the website is in my profile ("View all" button, top right)
I was prompted to take the tax interview again, also according to the email I received it's necessary to update tax information every 3 years or so, maybe that's why others are having problemns, I think it's better to file a ticket and wait for a response than redoing the interview by yourself, since my status said "vaild" the whole time and changed to "invalid" just now, maybe, but it's better to ask support just to be safe.
Either way, thank you for the response.
1) This game was finished over 10 years ago, there are no more updates, sorry.
2) I don't remember but I don't think you can.
3) Hi.
4) You can check the link here: https://vosmug2.wordpress.com/ but I've had a problem where my invites don't seem to be working, so let me know if it works.
