There is a bug with Jennifer - you get her warp ability after the first level up (supposed to be the 2nd).
Sweet that it doesn't use energy - is that intentional?
The first mission where you have a choice between missions is bugged - it'll freeze if you win the "moderate" difficulty option. I don't know if it'll screw up for the easy option, but it was hella annoying since I did the mission twice.
