I want to answer your question about what is Boosty,
Boosty is like Patreon
If you make a Boosty Account, you can post there stuff you post on Patreon(peeks and ost for example). The problem with the previous comment from another guy is that they don't know that you still cannot receive money from Russian payment systems, so the whole Boosty idea goes to trash bin since it is the only reason you would like to create one. You sure have Russian fans who love your work and want to support you, but due to irl clownery they cannot do that at the moment. Maybe Boosty can allow you to do that, but i don't think so, maybe im just stupid.
anyways great update guys, thank you for keeping the main game fully free, i respect you and i will certainly donate some bits to you once it is possible.
