Full Wound Addendum: This is the record I set the next day. I'm not running any faster. In theory, I could still reduce the time by using instant turns, but I'm already tired after 2 days. Maybe I'll post a speedrun on level 2.

According to my observations, in the 3rd secret and during the escape, the fastest way is to wait for the green dog to jump over you, and then grab and throw.

All the best!
