I never hit that point in either game...are you being sure to get all the survivors and crystals you can? If you do that I'm pretty sure you'll always be able to advance if you never skip a level, even if you don't always get golds and miss a survivor or crystal here or there.
Oh yeah i never hit the wall either (I perfected levels as i went along all the way up to about level 45).
I have no idea what this game is all about. Downloaded two days ago and found it to be pretty addictive. I am on level 36. I actually like the on-foot levels better. I think if they make the entire game on-foot, it will become a MEGA-HIT like those of Mario/Rayman Legend. Add Coop and more enemies and it'll definitely be addictive.
Overall, I thought the game was a bit on the casual easy side. There are some puzzles that need to solve and that's the only thing that keep the game from flowing smoothly.
I agree, a straight-up Velocity platformer would be awesome. Would love to see them do that! And i believe the game is supposed to be pretty easy to complete. The challenge comes from perfecting it.
