If I remember correctly, I did see mention of him trying to release an updated trial sometime in March, but I might be having monke brain and misremembering.
In any case, I'm just waiting patiently, there is a meme of "game never-ever cause sick jap dev" but in this guy's case, it's legit. I'm not having my expectations broken just like last year, when the game was meant to be released March 2020. Even though I was calling it back then that it would be delayed, the slap I felt was from that asshole called Covid.
Eta for full game release? By this stage, it's anyone's guess. Guy has been quiet since late December, so either he's putting in a massive grind to just get this fucking thing done, which he has done before (going radio silent to work on it), or there're health issues again.
