The problem was indeed .NET framework 4.5.
My thoughts and impressions about the game:
+ The ship is moving too fast! It's hard to get myself exactly where I want to (near an asteroid).
+ I've read that I can move my control unit to an asteroid. How the hell do I do that?
+ I like how you can cut through asteroids and they become separate physics bodies.
+ Could be nice if the game would pause when I'm alt-tabbed out of it.
+ Space is square?
+ Oh I found another ship!
+ Oh, it's moving fast, too.
+ I see a turret. It's not shooting me?
+ I just destroyed an enemy ship but didn't salvage anything.
+ I've read that I can extend my ship. How do I do that?
+ Suddenly my turrets shoot at a faster rate.
+ I guess the ship is so fast because it's made to be plaid zoomed-out and in a huge space.
+ Interesting how turrets are both for mining and for destroying enemy ships.
+ Oh, another ship.
+ It just rushed forward and crashed into my ship.
+ Last one didn't shoot me.
+ OH GOD ITS SHOOTING ME.
+ It's not moving it's turret to trace me.
+ I pressed escape and quitted accidentally. Could be nice to have a prompt.
+ Could be nice to have a way to pause the game.
+ Oh, this scale on the lower-right is a zoom-o-meter!
+ A red circle, probably a planet. I should go there.
+ Oh, a star!
+ Turns out that when I navigate out of my current area in space, another asteroid field is generated in the sector I'm entering.
+ Space is literally littered with asteroids. It should be generally empty, no?
+ The planet is so far away! I wish my ship could go faster.
+ Perhaps an FTL drive that lets me blink somewhere else in a matter of moments but has a cooldown?
+ Generating new chunks is rough. This half-second freeze every couple of seconds is getting annoying. Smoother generation could be nice.
+ I wonder how far do I need to travel for the game to actually slow down due to huge amounts of gameobjects.
+ Why does my ship slow down when I release the throttle? I'm in space, and there shouldn't be any air resistance.
+ The radar is very nice for navigating when zoomed out and not crashing into things!
+ It's nice that the ship has no reverse (so I can't over-do the brakes)
+ After reading this topic, I've started pressing all keyboard buttons in order.
+ I stumbled upon the 'C' button. Nice!
+ OK I made some ship expansion and added laz0rs.
+ I still don't know how to move my command block to the asteroid.
+ I wonder where can I see a list of available crafting recipes.
+ I wonder what the 'M' key does. The game freezes for a moment when I press it, but nothing seems to change.
+ So I just accidentally crafted a processor.
+ Placing it on the ship doesn't create an input and output box.
+ Do I need to craft it? How?
+ Hey, I see a whiter-than-usual mineral on this asteroid.
+ What the hell, my lasers aren't firing!
+ Nevermind, I'll mine it with my hull!
+ That was fun. I destroyed my ship's nose though
+ OK. The processor just made raw oil. What the hell is that and how is it useful?
+ That extra-white minerals was Silica.
+ I can't process it.
+ I just processed the raw oil into plastic.
+ This game's crafting system has alot of potential.
+ It could be nice if you could process an item in more than one way. Then you'd have to program the processor to whatever item you want to get out of it.
+ I just accidentally crafted a container like the ones around my processor.
+ The crafting system just broke (I can't craft what I crafted before anymore)
+ I want to move my existing processor somewhere else so I could chain it with the one I crafted.
+ I'm restarting the game.
+ I just realized that the crafting system didn't break. I tried to use plates instead of iron in the recipe.
+ It could be nice to have a tooltip for items in the inventory (to identify what they are).
+ OK I just figured out that I move stuff by holding down the left mouse button over them and then dragging off their current position.
+ I just tried to move my power unit and the game crashed.
+ I restart
+ I manage to reproduce this crash
+ I restart
+ I stumble upon an enemy ship. It fires at me very quickly and destroys my command unit.
+ I can still control my ship O.o
+ I fly next to it and build an extension right through the enemy ship
+ Now the enemy ship is in symbiosis with mine. It's stuck in me! :D
+ The volume of the laser firing increases when I have more lasers. This is bad.
+ Oh, now I know why my cannons stopped working before. I was out of energy!
+ This game could have awesome survival-multiplayer.
+ When I have a processor processing iron ore, and I have iron ore in it's output because it's another processor's input, I seem to lose the iron produces by the first processor.
+ I got bored and quit.
