Well i can understand you. I remember signing in on page here alot of time ago, the geting back here and seeing est. date of relese on steam as aprill. I backed it instatnly waiting. Game did not arived which was well not finest thing. Hoever i do understand why it did not arived, they are indead very small team and are doing theyr best (i hope so).
Thro last 2 months i have read alot of updates and seen few of streams, and i must admit i am impresed abaut how much they did. I wuld love them to post game on the steam on the form as you play - but you cannot buy it yet. They must have good reason why they are not doing this, maybe they cannot, maybe they are afraid of posting this as well preaty much basic playable version.
This game have to of potential and i am sure sooner or later it will be given to those who backed it, hoever we need to be paitient. While i am frustrated that theyr post are becoming infrequent those which are realeased show huge changes.
Ofcourse thats what i can say now, if i wait few months more i myself will become angry biter and sarcastic (and my soul will be corupted_, all becouse they forced me to wait for to long time, for the game of my dreams.
So, the only think i can tell you is you need to be patient... Maybe they will creat some kind of small arena to play on with ships for those who backed and have no infiltrator (some kind of skrimish mode) but i doubt it.
