For the most part, I am loving it!
There are only a couple of things I'm concerned about.
1. Parachutes seem to fail (break off after deploying, both before or after full deployment) randomly, though I admit it could be I am doing something wrong. So far, it's hard to tell which. More experimentation is needed.
2. Maneuver nodes seem to be... I want to say unfinished? In KSP 1, there was a UI that allowed you to make subtle adjustments to the node after creating it (as part of the mode control). I can't find anything like that in KSP 2, and am having a difficult time making small changes to a node. It seems like the only way to interact with it is to drag parts of the node itself. Someone please tell me I'm just missing something.
Everything else is awesome! rocket building is fun and intuitive, flying the rocket is great, the graphics and sound are phenomenal, and the countdown is a fun addition!
