The past few days have brought several significant changes. First, we have three game versions now: early access, closed beta and an internal developer version which as you can imagine is the most content rich one. But what's more important is that closed beta version is already way ahead of the early access build. This means that the playable version goes through a double bug hunting filter, but also still fits within our timelines - that's a solid attribute of a controlled release schedule by the way. So both content and game mechanics get properly tested and you get to play the most bug and glitch proof game build that can be possibly provided at the current stage.
As it was said before, we are keeping up a good pace and the beta version is currently ahead of the early access by two planes (Yak-1 and Pe-2) and two game modes: Quick Mission builder and Multiplayer. If we keep this up we’ll have a quality game to release. Meanwhile, flying the Pe-2 is a peculiar pleasure. It's hard for me to describe all the tiny traits of its character with words, so let's take landing for example. Somehow it makes me adore and hate this plane at the same time. Landing speed is so low that it nearly matches the stall speed, that's why landing actually looks like a series of bounces on the airfield or more like a landing turns into a control semi-spin at ultra-low altitude (it may sound like a joke, but it's pretty much true).
