Just looked this up on Steam. Looks good. I personally prefer the Steam approach. Get to have a look at the game on F95 and get a feel for it. Then pay for the game up front and be done. Clean updates through the Steam engine. You've supported teh game and dev, and the dev isn't trying to milk supporters through a subscription model, like we've seen too many times.
Added to the wishlist on the strength what I've seen on Steam, gonna give it a play through to get a flavour of it. But yeah, first impression is looks promising.
