Chex Quest 3 - Invasion! - United Cereals (level 2)

This is the second level of Chex Quest 3.

I had a difficult time finding the latest version that works. A couple of the earlier versions had a bug where it didn't register when you picked up a key. In one version, this happened as early as level 1, but in two other versions, it happened in the final level. All of these versions were .wad files. Only when I ran the application version of the game (.exe) did I not encounter any problems.
