See the video that comes with this explaning how this was achieved:
This entire game fits into a 64 KB executable - including all textures, levels, models, animations, sounds, music, and code.
It’s a retro shooter with 3 levels, 1 boss fight, 4 unique enemies, 4 weapons, and a handful of power-ups.
Minimum specs
- Intel i5 or equivalent
- GTX 770 or equivalent
- 8 GB RAM
- 64 KB disk space
There are two versions: compressed (64 KB) and uncompressed.
The compressed build might trigger antivirus warnings, so you may need to add a folder exception.
If you’d rather avoid that, an uncompressed version is also available.
