I like the drama of the lead up to the last crystal which seems to always be a 1-way ticket jump. I think it'd be fun if you played that up more. Maybe that last crystal pulses or an aura appears around it to build anticipation once you've collected all the other crystals.
By the same token, I want more of a payoff once I make the jump to get the final crystal; maybe something like a slight pause so I can enjoy my victory for a bit before the trials of the next level. Or the crystal could fly around me and then off-screen.
