Most of this level (from the green frog to the purple frog) was laggy, so it was harder to avoid obstacles since Lily could only move so fast through the lag.I have to wait near the end for the mine cars to move so I can cross to the red frog, so I get a coin to save time at the "Coins missed" screen.I have to wait for the two rats to move before continuing, so I run into the wall and move again on an odd frame, allowing me to double-jump out one frame faster.In most levels, this will find the next frog in order (green-yellow-blue-purple-red), but strangely, the red frog (last one) answers the call in this area, since it's closer to me than the yellow frog (right through the wall). While I'm being entertaining on the mine car, I croak to locate the nearest frog.Not only does the Quick Hop butterfly help me get on the mine car faster, but it also helps me provide entertainment while I'm riding it.I could have saved 16 frames in the beginning jumping over the rat near the detonator, but I have to wait for some rats near the yellow frog (think of it as a frame rule), so it wouldn't save any time.Level time: 35.80 (35.70 is possible, but would be slower in a full-game TAS).
But, since getting the 6 coins is 13 frames faster than the double-jump route at the Coins Missed screen, the coin route is faster overall.
This level is required to continue on, but at least it's short and lag-free.Double-jumping inside the blue object doesn't put me on another layer, but simply allows me to move earlier as soon as the object I'm inside of moves out of the way. I only use this once near the middle of the last level, Windup.
