Crash Bandicoot 2 (N.Sane Trilogy) - No Hit (Part 2) - Level 1: Turtle Woods (Crystal + Blue Gem)

Played on PC. Doing a no hit/death playthrough. Rules relate to single-level runs, i.e. if I die I have to restart the level. To get the Blue Gem you need to finish the level without breaking any boxes. Normally I would just die after getting it and go for the regular gem to get everything in a single visit but since this is a no hit and no death playthrough I can't really do that.
