Monkey Business concerns a monkey on the receiving end of some simian psychology experiments. It's extremely incomplete: there are a couple of brief scenes establishing your problem and then a "to be continued" message.
What's there is solid enough, but there isn't really very much to do; the one semi-puzzle could be solved entirely by accident. This puts the game on the short side even compared with other deliberately-incomplete works such as games entered in Introcomp.
If there's a longer version of this game eventually, I might be interested to see where it goes, but the introduction as it stands is not a very substantial play experience, which is the reason I'm not scoring it higher.
