Really fantastic game, am playing for a couple of days too now and love it, but the wormholes don't work that well for me ... I use them, and then got stuck twice already when I did a jump which gets me back into the first galaxy, but can't fly back because the gate back is still locked. Just right now it was the first jump I did, so seems a bit like russian roulette with pressing the trigger 5 times if I want to explore more galaxies after the use of a wormhole. Am using FC III+ to get anywhere.
Also if I would jump into the last galaxy straight from the beginning I guess I would just be cannon fodder for the enemies there, since I wouldn't have a shield yet or anything else, wouldn't I?. Also the Traders are a bit irregular, I went all the way to the 4th galaxy, and checked every single waypoint, without finding a single trader, so had a bunch of cash but couldn't use it. Luckily I've found at least a basic shield by then in some loot, wouldn't have made it otherwise.
This sounds a bit negative, but in fact I'm loving the game, and enjoy it! Just saying in its current format I wouldn't be able to progress without a Freezer.
