If you only play single player, then go to another review, this review is entirely about co-op for the time being.
TLDR: The game in co-op has input lag. If you are looking forward to playing co-op in this game, please don't buy it yet.
I'm not going to review the full mechanics, graphics, and options of the game just yet because I haven't gone through it all. However, I want to bring attention to a SERIOUS flaw in the game's netcode at the moment.
I love Q-Games, and own most of their ps3 titles, as well as a lot of their PC titles. Please keep in mind that it absolutely pains me to write this but it must be done.
Currently Nom Nom Galaxy (NNG) has input lag when you play in co-op. Everyone, even the host, experiences this input lag. It can range anywhere from 200 ms - 500 ms (rough estimate) depending on the connection. This input lag is noticeable and gets very annoying overtime as it makes you miss jumps, and makes building your factory a laggy experience. The developer Q-Games has stated that this is currently the case because they have had a rough time with netcode, as the way they do it for PS4 doesn't work here on PC.
Here is the discussion thread: http://steamcommunity.com/app/226100/discussions/0/541906348050084830/
The developer had every opportunity to delay this game, and fix this massive issue before launch, but chose to release it in it's current, annoying to play in co-op state. This is unacceptable Q-Games. So I will continue to warn people not to buy your game until you decide to fix this issue.
