A neat little final challenge for 1.0. I've always had a soft spot for this one, perhaps due to the happy song or interesting structuring and gameplay. I find that the upside down ship probably could've been introduced in Base After Base or Cant Let Go, as it feels strange to introduce something like that in the hardest level in the game. Perhaps I'm overthinking this aspect, though. Neat little test of what the player has learned throughout the game, though similar to Base After Base I do not think this is a big enough difficulty jump to stick out as one of the more memorable levels. The ships here feel underwhelming as well, I see no reason why the difficulty of them couldn't have been pushed forward. Some actual gameplay with the flipped ship would've been nice. However, as stated before, I do have a soft spot for this, and it still has the quality a RobTop level would have.
