A downloadable game

This is my submission for the gbcompo21 game jam.  It's a short puzzle game set in the near future, AD 1999.

How to play:

Download the ROM, and either use a flash cart with Game Boy or Game Boy Color hardware, or use a Game Boy emulator like BGB or SameBoy. If you use a flash cart, it needs to support ROM bank switching and battery saves using MBC5.

Also how to play:

Use the D-pad to move around and push boxes. Press A to interact with NPCs and B to propel forward and cross gaps in the floor. Try and get to the exit space of each level. If you get stuck, press Select to restart the current level.

Development:

The game is written in C using the GBDK-2020 development kit, and the gbt-player music driver.  All assets were made by me during the jam period. I used GBTD and GBMB to make the tilesets and maps, OpenMPT to compose the music, and BGB for debugging.

This is a "black cart" game that runs in full colour on GBC, or in monochrome on DMG. In practical terms, this means working within the more restrictive CPU and memory limits of the DMG,  ensuring that all graphics work in both monochrome and colour, and forgoing some GBC-only features like tile mirroring.

The full source code is available for download. To build the ROM from source, you'll need to install GBDK-2020, and adjust the paths in the Makefile to suit your environment.
