Simple rocks-and-diamonds game

MrMatt is a simple puzzle game in which you tunnel through caverns collecting diamonds while avoiding being squashed by falling rocks. It is based on Repton (but without eggs and monsters).

I originally wrote MrMatt for Acorn RISC OS. Original and updated RISC OS versions are available.

The name of the game is an abbreviation of my school’s. “Repton” is also the name of a school, but I don’t believe the game was named after it!

Credits

The sounds are from Freesound, lightly adapted.

Installation and use

The game provides instructions on how to play.

Binary installers

Installers are available for GNU/Linux, macOS and Windows. See the latest release:

• The GNU/Linux version is a single binary; you need to make it executable and then either copy it to a directory on your path, or run it directly: chmod +x NAME-OF-FILE; ./NAME-OF-FILE
• The macOS version is a disk image file containing an application. Drag the application to a suitable location (e.g. your Applications folder). macOS will probably refuse to run it until you have approved it in System Settings→Privacy and Security, under “Security”.
• The Windows version is a single .exe. Unfortunately it is detected as a virus by most virus scanners, including Microsoft Defender, because Python apps have often been used to distribute malware. Hence, you will probably have to turn off virus scanning before you download it (to prevent it from being immediately quarantined or deleted), and then add an exception for it. After that, you can put the .exe file in a suitable location and double-click it to play.

Python package

If you are a Python user, this is the simplest way to get MrMatt on most machines.

Install with pip: pip install mrmatt, then execute the command mrmatt.

Creating and editing levels

Currently, to play edited or new levels you must have a source check-out of MrMatt from GitHub. (If this doesn’t make sense to you, sorry! I hope to provide a simpler way to edit and play new levels soon.)

The level files are in the mrmatt/levels subdirectory of the project, and are Tiled level editor files, so you will need to install Tiled to edit them or create new levels.

Having saved an edited level you can install the Python package with pip install . or run it directly with PYTHONPATH=. python -m mrmatt.

Some notes about level design:

• A set of levels is numbered according to the lexical order of their file names.
• The supplied levels have a brick wall all the way around. This is conventional but not necessary: there’s an imaginary brick wall around the outside of the level already.
• Levels need exactly one start position, given by placing the Win character.
• No checks are done to make sure a level is possible to complete; for example, you can place diamonds surrounded by bricks, or have safes but no key.
• A complete level set requires a Tiled tileset and corresponding graphics. You can simply copy the tileset file MrMatt.tsx and PNG graphics from mrmatt/levels.

I welcome pull requests for new levels.

Improving MrMatt

New levels, usability improvements and translations are welcome, as are usability improvements: for example, the ability to rebind keys would be welcome.

Some levels useful for testing are in test-levels.
