Many stuff to answer! Let's start from first post

Fixed various bugs reported by fabula. About the hearts, you don't actually need to have the maximum relationship right now. Since you could answer badly earlier in the game I didn't want the players to feel frustrated because they can't reach romance. You need 75% of relationship (not sure exactly how many hearts it is). On a related note, I definitely want to move away from this "pick right answer" system for RPGs. But this is another story !
I don't understand the staggered tooltip bug, but the crash was fixed at least.
New Mac Retina bug: hmm interesting, is something I need to report to the Ren'Py coder himself. Also the other bug you mentioned. Will do it today!
About the rest/ship idea: yes is a good idea, probably better since people NEED to use the ship to go on. Will add this now
I've fixed the Aravorn/Zoltar confusion in the Empire dialogues. Fixed achievements texts too.

Yes, I might also add some more "global" ones like the "this is our story" and such
Troyen wrote:The credits look like they start a little bit into the credits animation, with both Celso and Götz on screen. Not a big deal, but at the end of the credits, it starts to loop again for a half second and then kicks back to the main menu, so maybe the timing is slightly off.
Haha I've tweaked that a lot of times, but when I add a new line of credits (for example forgot about a GUI artist) it goes off. I'll do it as last thing

When I gain my first bit of experience, I have 28/100 experience, but the red bar is 72% full (the right side is 28% clear). This looks backwards from what I'd expect, where a red bar fills up instead of goes down. Level 2 is worse, 102/200 exp is something like 35% full?
You're right, I thought I fixed it, but is still off. Need to check again.
About the musics, I haven't changed that code, so I think was always like that. Here seems fine, I wonder if is some Mac only bug of Renpy... hmm.
The "static" sound was supposed to be a cold wind, but seems is not good (other people said that). Will try to find a better SFX!
