Erwin, I was looking at your Patreon and some of the content says it is "locked" by T2 and T3, yet I only see an option for T1 supporter membership. I'm a bit confused.
He wrote he'll suspend that option for few weeks cause he is absent, and doesn't want people to feel robbed. I'm in the same boat... I wanted to get my hands on the dev version as soon as I finished the public playthrough but nope. Gotta wait :D
