Hi have you heard more? I haven't risked it yet but I heard about Paypal problems that includ these games, so when I heard about patreon I still hope we get an update.

From their most recent Patreon post:
"This update was supposed to be something relatively quick, made to avoid having long stretches of time with no new content, but like, I'm a mess and so...
Plans are still as they where, a new small update next time, ideally somewhere around the end of may or middle of june, and then 0.6 as something bigger."
I'm not a Patreon member or anything, I just checked it on a whim one night and saw the update. If there isn't any update on this site by June, it might be worth to look at their Patreon. It is linked in the description, and I'm gonna guess they post public updates anyone, regardless if they support the game or not, can see.
