Chapter 7. Don't Be a Clock Blocker
We've taken a baby game like Memory and made it slightly cooler by changing the straight-up match mechanism and adding a twist: matching disembodied robot parts to their bodies. Robot Repair is a tiny bit more interesting and more challenging thanks to this simple modification.
There are lots of ways we could make the game even more difficult: we could quadruple the number of robots, crank the game up to a 20x20 card grid, or rig Unity up to some peripheral device that issues a low-grade electrical shock to the player's fiddly bits every time he doesn't find a match. NOW who's making a baby game?
These ideas could take a lot of time though, and the Return-On-Investment (ROI) we see from these features may not be worth the effort. One cheap, effective way of amping up the game experience is to add a clock. Games have used clocks to make us nervous for time immemorial, and it's hard to find a video game in existence that doesn't include some sort of time...
