Fun hovercraft mechanic that gets 'upgraded' on repeated plays. The course stays the same, but you see it through a different lens each time. Lots of replayability. A few bugs (the start button wasn't responding after a playthrough for me) but that was fixed with a re-load of the game.
Interesting how the core loop makes you choose what way you downgrade your craft, from vague descriptions that only hint at how you'll be affected. Upside down mode is brutal!
Fits the theme well too!
