The update is making good progress, the forest level is huge and will feature caves, several wood cabins you can enter and LOTS of trees.
The new mode will be thunderstorm/rain, it's damn creepy when the lighting flashes and you see Slenderman pop up for a second, then you turn around...nothing...turn around again...there he is.
There will also be a small, but significant mechanic change. Currently if you look at him from a distance, you can easily escape his stare, but he will teleport like crazy. In update 4 he will instantly kill you if you look at him for too long from a distance, but won't teleport so much. The swipe-to-escape will now only happen when you get jump-scared.
Still not sure when the update will be ready, i guess when i'am happy with it. Slender Rising continues to be a worldwide success and i want to say thanks again to all players.
