In Act 2, I can't get down the trick where you land on the corner near the spikes before jumping up to the blue moving platform. It's the same with the other act that uses that trick.

Any tips on how to get it consistently?

For me its all muscle memory, but for act 2 you can take a safe strat and just lose one cycle, you hang on the corner jump up and hit left then right and aim for the corner. As for the jump to the block from the corner, you wait til the block above you reveals a bit of the buzzsaw as its ascending.

Ah, thanks! It's just a hard strat that I was practicing for a little bit.

I didn't get good at it, until i was able to get sub 6

Yeah it's mostly just practicing until it's muscle memory

Its only muscle memory for act 5 but for act 2 just take the set up and loose like 4 secs
