You’re at a good spot right where you are on the screenshot. What you now do is:
- Hold the action key (i.e. “elsewhere” on your screen, if you use touch input).
- Jump.
- Steer left.
- Do not release the action key (or move past the platform) until the platform is fully below the player blockers.
A small variant:
- Bring the platform a bit more to the left so it’s about halfway between the two block types.
- Jump, then immediately hold right and action (can basically press all three at the same time).
- In the middle of the jump, once past the player blockers, switch from right to left. You usually can also release the action button at that time.
That’s what I thought of when placing the arrows.
Either way, you’ll jump through the platform destroyers, while the platform will rise through the player blockers - and you’ll end up right back on the platform.
