Making engaging puzzles isn't easy. ARKEO features a unique carry mechanic that is used in many aspects of gameplay. Experiment by interacting with items and see what you can pick up on your adventures. #gbstudio #gbdev #gbc #indiedev #pixelart

Some screenshots of my #Metroidvania made for the #gbcompo25. The game was created with #gbstudio. I tried to improve my #pixelart for this #gameboy project.

OrmBlok is a new game I made with Mike Liesz over the last 3 months for GB Compo 2025. benjelter.itch.io/ormblok It is an arcade puzzle game where you build a playfield with blocks and then play through it as a worm. Hope you like it! #gamedev #gameboy #gbcompo25

RGBDS 0.9.2 released! It adds some new features, including more string functions in RGBASM and an excludable "background" color in RGBGFX; fixes some bugs (particularly with RGBGFX); and makes some things more convenient. github.com/gbdev/rgbds/re…
