I'm 9th on the leaderboard with 5 hours of playtime. But I don't have a single achievement, even though I should have one. Does anyone know what's going on?

Unless I missed something I couldn't see an option in invert Y axis. If its not currently available then perhaps this could be an option for a future version? :)

Looks like a great game, sadly, it is completely unplayable without the option to invert the Y-axis in my personal opinion.
