Strong aesthetic here - and it looks like you also used low poly / 2d menu style with your entry as well. Other than that, I found it hard to understand what exactly I was doing. There was a lot of information thrown at me at once and I didn't know where to start. I thought I had an idea, but it didn't go the way I was thinking - which was unlocking a mission.
Personally, I'd steer away from introducing the game with a ton of text - and I didn't find the text box and option selection that compelling - I just wanted to skip it as fast as I can so I can get through your game and move onto the next - but to each their own.
Anyway, menu/text heavy games are always difficult to convey - my entry somewhat suffers from that too, but a good tutorial or walk through on showing the basics would be gladly appreciated.
Thanks!
