Bit’s Blitz – Puzzle Game

In the third year of my Computer Science BSc (2013) as part of the Commercial Games Development module, we were placed into groups and tasked to produce a computer themed game designed for children. Each of the group members had to produce a game design document, one of which would be chosen for the group to develop. My group consisted of me, Aaron Ridge, Michael Killingbeck, Andrew Woodrow, Joshua Twigg and Alex Lynch.

The group decided to go with my game design which was inspired by the classic puzzle game Chip’s Challenge, with the idea being to reimagine it and modernise the graphics.

Game synopsis:
 “‘Bit’s Blitz’ is a fun 2D puzzle game following the escapades of its protagonist ‘Bit’. The game takes place across a series of levels increasing gradually in difficulty, gradually introducing new game-play elements. The player controls ‘Bit’ around a grid, constrained by a series of maze-like blocks and hazards. ‘Bit’ must successfully collect all the computer components that are scattered around the level and then repair his computer to proceed to the next level.”

Details:
Developed using C# and the XNA framework for the PC platform (Windows XP+).

 

The nice thing about this game design was that we could focus on the puzzle aspect of the game, time and imagination permitting, due to the simple overhead on technical implementation. The tile-based game engine was written from scratch using XNA, utilising XML data structures to store level data and a custom made loader. A cool and free little program called Tiled was used to ‘paint’ the level layout and export it into our XML format. I’d strongly recommend this to any considering 2D tile-based games for constructing levels, having said that, it’s a nice programming exercise to develop your own editor if you get the chance.

All gameplay aspects including animations and particle systems were programmed for the game, using no other libraries except XNA. I designed the game framework based on the State Design Pattern which worked out really well and continue to use it for game development.

With the use of XML and Tiled it allowed us to churn out level designs at an alarming rate and the final product has over 20 levels! Not bad considering the 2 week development time. When giving the presentation of the game, we literally only had time to demonstrate about 5 of the best levels, odd considering level variety tends to be in short supply for prototypes.

Sound effects were added (free assets) however I’ve removed these from the video and added music since honestly, they weren’t brilliant! The above gameplay video demonstrates various levels (played by me). I could barely remember most of the levels so it’s pretty much a blind play-through with some genuine mistakes.

For the project we all chipped in and the group worked well together. The game was never released or published anywhere, though if anyone is interested I could stick the executable on here for download.
