cant even reach the menu before it glitches or crashes

You have to register a 3rd Party Account (service provided by uID.me) even if you only want to play single player.
I don't get an activation code sent to the email address I provided so its actually kinda buggy.
I've been stuck in the game menu for 30 minutes and can't do anything because of this extra registration process.
I actually want to play the game but this process is so annoying that I wouldnt recommend this game at this point.
I got no response from Author/Support of this Game until today.
So if you get a key in registration process you might want to take a look at the game.
Its sad because the game actually looks fun to play.

Update: The Author left feedback and has made every effort to help but I refunded the game.

I had a lot of fun playing the game. There is something relaxing about clearing the planet from aliens :)
The flight mode is my favorite, and fighting alien bosses is very entertaining! I got to the jungle flight mission now, and I will write an update once I finish all of the missions! Highly recommend the game!
