Doppler's Fort through Infrared Springs, Give it your best shot, and Trapped (see next level description for explanation)
Edit: I just realized you need to be on measured or seen for the 'bridge' to 'collapse' on Watery Chasm, which has to happen in order for you to finish the level.
If you find any I missed, tell me, but I think these are the only ones. You can try levels in measured or seen that can be done in normal, but not all of them are possible this way. Still, I'll give you 10 awesome points for each 'normal level' you complete in measured and 25 awesome points for each level you complete in seen. Also, I'll give you 15 awesome points per bronze achievement, 40 awesome points per silver achievement, and 100 awesome points per gold achievement that you complete while doing my levels. Finally, I'll give you 1000 awesome points for doing my levels in under 13 minutes (I don't know if this is even possible, but it's ~30 seconds per level), 750 awesome points for in under 21 minutes, 500 awesome points for in under half an hour plus one minute, 250 awesome points for in under 46 minutes, and 100 awesome points for in under and hour plus a minute. (Is there an awesome point bank hiding in these forums? I seem to be running out...)
Well, good luck, and here are some tips for the tricky levels:
-Doppler's Gort and Geyser Bay kind of rely on luck. If you don't get through it one time, try not to go at the same time you went the last time, because you'll get the same result (same result=death/fail) if you do.
-Infrared Bay is the most frustrating VP level I've ever made (thus the achievement for it), and it's a big time-waster. Other than that, it's actually relatively easy if you know what you're doing. You've gotta get it on the first try or else whole minutes of your time are gone.
-Choose a way to go through the volcano before-hand.
-I'd say Over the Volcano is pretty much the same difficulty as Under the Volcano. Through the Volcano is harder, but mostly more frustrating, and it has the possibility of wasting more time than it saves.
-On Melting Overhang, go diagonally across that really fast water trapdoor thing.
-On Clake, there is a path for you to follow in and out of the lake. You've got to be quick going through it.
-On Through the Magma, hit a fire block, then use another fire block to melt the ice that was created and repeat this process to get to the finish. You need to be smart about how you use your fire blocks, and you also need to be quick.
-On the beginning of The Core of The Volcano, hit the right fire block, then the left-down one, then melt the right fire-block-turned-to-snow and use the fire block past it to melt itself (since it gives you more fire time than it takes for it to turn to snow). After that, once you get to the upper-right corner of the screen, melt the fire block on the right first. It's smooth sailing after that if you know what you're doing.
-On Give it your Best Shot, you've got to go as fast as you can whilst avoiding the cannon's bullets diagonally and to the left, hopefully unlocking the doppler gate.
-When you see really-close-together garages, those are 'walls' that don't take up a whole tile of space. Clever idea, right?

-Complete Fishy Lake without the fish so it won't slow you down.
-Scoot in between the bullets before they fire again on Cannons of Doom.
-MORE Cannons?! is just one of those levels where practice makes perfect. Even I had to learn many of the tricks to get past the level, but when I did, it was actually kind of easy. Instead of telling you all of them here, I'll let you find them out for yourself.
-Take advantage of the diagonal-like bullets on Fish Food Bridge.
-The final level, Training Grounds, is the hardest. You've got to scoot in between the bullets and wait for the perfect time to jump out and grab the fire power so that you can melt the ice block. After that, it takes a lot of patience to wait for the perfect time to run across to the first section of land, then you have to have good timing again in order to get to and fro the other fire block. After that, it would get a bit easier if not for the huge pressure of finally finishing the last of the levels. Although I'd say that Geyser bay is the most frustrating level on its own that I've ever made in VP, dying at the end of this level is definitely the most frustrating way to die in my series of levels, because you have to get passed the killer cannons and wait forever for the right time to pass through the lake again, plus, if you hadn't died, then you would have won the whole thing.
PS: For anyone reading this who doesn't know what VP is, it means Velocity Raptor.
