We call initial momentum of the flight as warm up phase which I stupid enough to use it and died because of spinning fan on top of my head. The melee upgrade bug is you destroy its crate but didn't get it?

On my first playthrough, I actually wasn't able to break the crates at all. In fact, I coudn't break the crate at the top left of the beginning of the stage as well. It had me really puzzled on why I can't proceed with the game until I restarted and found out that I can break those crates.
Strange things happen when you restart (maybe it's got something to do with me losing focus on the game's window on the first time I ran the game).
