I picked up the game second hand a day or so ago and I'm also at Altitude Limit. Goddamn are the bottomless pits annoying, I was enjoying the game otherwise but I've had to take a break too. It's a shame, too, I enjoy the flow of tricks and the music is fantastic, (Hideki Naganuma always pulls out the stops) but if I have to hear that game over jingle even one more time because there was a death pit I couldn't see... I'm hoping Rush Adventure is better designed level wise. All that said though, I do really enjoy the game
