Eh, the way you put together sentances is
strange but not particuarly
hard to understand. If you're curious about that sort of thing, a native speaker might have said something like:
"Well, I think this was the worst situation... I pulled lever number one: Ok, the walls are gone -- the level now looks like one big room. Three seconds later I pull lever number two: The whole level is flooded with lava. Well ... next time I'll ignore the levers."
There are LOTS of variations on word order and word choice that sound natural, and lots more that sound a little strange but are more or less understandable. There's much variance, especially in non-formal quasi-conversational writing. Heck, in writing fictional dialog, you can make someone seem foreign or accented by their words, the order that they put them in.
As for the levers, yeah, they can suck. However, some of the worst of them are forewarned by XXXX, so pay attention to those.
XXXX = the messages you get when you enter the level, some of which indicate the presence of a certain kind of lever. For example, a rather nasty lever similar to the one you got here which floods the level with acid is heralded by some line about decay in the state of denmark.
