Am I missing something?! I can't seem to find the last 5 coins on Burn Alley i've beaten all the other dev scores but this one! I have no idea how many times I've gone through this level but I'm always 5 coins short, help please! Here is what I do, At 30% I get 5 coins, 40% 5 more coins, I then RJ at 43% get 5 more coins, 56% 5 coins, 64% 5 more coins and 69% I get 5 more. So far I've got 30 coins, from 77% to 96% there are pillars that have a total of 20 coins and I end the level with 50/55 coins
50% fellas. Edit: It's tricky. I tried to do it again to beat the dev score and you have to swing about the first geyser and then rocketboost. There may be an easier way but that is how i beat the dev score. Good luck guys.
Just remember, the stalagmites (upwards pointing) indicate you should rocket-boost, and the stalactites (downwards pointing) mean you should drop down, cause there's something important below you. They pretty much guide you through the level in such a way that you end up with all the coins.
I had the same problem BUT... i found the coins. I found them at the part where there is a Stalagmite right in front of a geyser .............. /\ ----------/ \----/*\----| usually you would just hit the geyser... But you have to boost before you hit it and you will find the five extra coins. This occurs in the first and last lava level. Hmmm I hope those were the levels you were talking about. Hope this helps
