The game features three items, a mine, a booster, and a triple boost. My goal when designing these items was to give players a way to catch up if they fall behind, or lay traps if they're ahead. If a player is in first, it's more likely that they'll get a mine, and if they're in fourth it's more likely that they'll get the triple boost. 

My proudest achievement of this project was getting a working place tracker for four players. No matter where you are on the track or what lap you're on, the game always knows what place you're in. I accomplished this by first dividing the track into segments. The segments are ordered in a linked list; you can only move from one segment to the next in order (forwards or backwards). The one exception is a segment that can be skipped to account for a shortcut. Then the game compares the players using the following criteria:

Lap number > segment number > relative distance along the segment

Were I to continue to develop this game I would like to add more items to fill out the pool of potential drops, and also develop a system that calculates item drops based on how many players are in the game, not just by what place they're in.
