Okay.

1. The ship jitters when still.
2. The ship can be damaged when a new level starts if the prior level ended with the ship in a "humorous" angle.
3. The ship rotating horizontally (not the turning upside down or anything) gets a little distracting visually from the motion.
4. Thrusting down on pads should be programmatically disallowed -- it damages the ship.

IMO the wobbles and stutters of the ship are too frequent and fast, and the general turning speed is too fast and not quite as smooth as I would expect. Not so bad on the latter part, but the former produces flickers.

The new thrust amount makes it a little tougher, but I got finished by a meteor anyway. They now 1 hit kills?

EDIT:
You might want to try alt-tabbing and clicking the task bar entry once or twice, and then the little minimized window. You get the following screenshot which is messy. DanJetX appears to suffer the same problem as Asphyre 4.
