In answer to the questions in your first query, no chosen boosters used and when the game starts there are 4 pink hearts in the bottom compartment and a cyclone? booster on the platform, which falls into the bottom compartment instead of jumping to the main part.
Just tried the game again and it is no different. Yes the platform on the right does jump, but not much and the booster just drops into the compartment below the platform, and not into the main part.
