Here's how I saved time. See the YouTube description for more details.
- Killing the penguins
- Keeping to the ground. Walking is faster than jumping.
- Jumping higher to fall faster past walls.
- Careful lag reduction on the Galaxy Man dudes
- Killing tadpole eggs to save a TON of lag
You can probably shoot the remaining two eggs and save a frame or two, unless that's really laggy. I forgot to try.
