Unfortunately, there's only five different maps. I know they were trying. Noteworthy is the effort it takes to have multiple stages of alien foliage growing the room, but alas this does not really add much to the game itself. Animations are a bit off. I notice that some characters walk in such a way that their feet slide while walking.
Sound is on the pathetic side.
The music adds nothing to the game. Lots of voice dialogue, but the voice dialogues are superfluous most of the time. One thing I couldn't figure out is why do the character grunt every time they pick up an object. Even a hairspray can cause a character to grone under the weight. Game play is a bit inadequate.
