Technically, you'll figure out hie enemies work, this game does not have RNG besides boss fights.

Avoid grabbing the star, it triggers the bonus horse ride stage.

On Richard rose, after the first cycle is done (when you destroy the balcony) Try to blow him up with the dynamite, saves so much time on the second cycle.

Third cycle, you can get him stuck and continuously shoot him without him moving. Idk how it works or how to get him stuck in this loop, but it's possible. Done it in my PB run that is on the leaderboard

Thats about it .. pretty simple
