I really appreciate the comment mate!
The last achievement category is Total Damage actually, I updated the game to reflect that and noticed that there was a bug and sorted it as well. For your last comment, I do agree so I changed the settings menu just for you!! (I hope you think the new one matches more)
In terms of the first two points, I wanted the game to be "bite-sized" and completable in one session hence getting the ship quickly. I guess I didn't expect people would want longer sessions so it's definitely something I will keep into consideration for future submissions!
I'm glad you enjoyed it and thank you for the very nice comments :)
