Hello and welcome to the first announcement!
Sadly it isn't a positive one:
The steam servers were under heavy load due to the summer sale these past days and we were unable to upload the game's files to steam.
There's a required time for steam to make sure our game is not some evil virus and so, to take all these things into account, Ikarus' release will have to be delayed by one more week.
Thank you all for your patience!
