The atmosphere is incredible! The feeling of isolation is surreal, the 2D/3D graphics mix is beautiful and the little cutscenes and interventions are awesome!
My only complain is... That it's too much ^^'. Yeah, I feel really lost, but mostly because I am actually completely lost, and even if it's cool for the first minute of gameplay, it gets old really fast ^^'. I only found 2 antennas, and it's more because I stumbled randomly upon them than a real search.
I would have enjoyed maybe more recognisable places, more hints, or just a smaller map maybe ^^'.
But otherwise, this is a really, really solid game. I love the ambiance, it is incredible what you've done in 7 days. Congratulations!
