Invasion of the Geminorons
Invasion of the Geminorons is a sci-fi puzzle game for Game Boy Color and Analogue Pocket.
The download includes a .gbc ROM file for use with an emulator or a real Game Boy Color, a .pocket file for use with an Analogue Pocket, and a PDF manual.

Hardware requirements
- To run on original hardware, the .gbc ROM file needs to go on a cartridge. There are no special requirements for cartridges; multi-game carts like the Everdrive GB and EZ Flash Junior will work, but so will any basic reflashable 32k cart.
- You need a Game Boy Color, or compatible console (e.g. Game Boy Advance). A monochrome Game Boy (DMG, light, pocket) or Super Game Boy will not work.
- The .pocket file runs directly from the SD card of an Analogue Pocket, with no cartridge required.
Emulators
If you don't have a compatible console, you can still play the game using an emulator. Install a Game Boy Color emulator and use it to open the .gbc file. For best results, I recommend using SameBoy or bgb. Run in Game Boy Color mode.

The game is built with GBDK-2020 and SDCC , and wouldn't have been possible without all of the people who contributed to those projects.

That opening gradient is impressive. Did you use scanlines?
Quite fun!
Thanks!
The graphics are masterful. I love the DMA? on the title screen. It makes it look extra colorful
Thanks!
I made a diagram showing exactly how the title screen works: https://geminorons.neocities.org/wiaf/#figC
Basically, it's using a single four-colour palette for the whole screen, but the colours in the palette get updated as the screen is rendering. So the art uses one colour for the background and one for the logo text, but you end up seeing two vertical gradients on screen.

Will it work on GB DMG?
No, it only works on Game Boy Color (and later compatible consoles). It won't work on earlier models like the original Game Boy, Game Boy Pocket, Game Boy Light, or Super Game Boy.

Does it support multiplayer?
No, the only game mode is player vs. CPU. The HTML5 version on the web has all the same features as the .gbc ROM file.
