That's the pitch, and it delivers. Super Impostor Bros is an original GBC fangame by lumpytouch that blends side-scrolling platformer gameplay with visual novel storytelling, all wrapped in the unmistakable aesthetic of Among Us. Three stages, hidden secrets in each one, and a story that actually branches depending on how you play. The collectible hook is clever: each stage contains 5 hidden ID cards. Custom cartridge, plug and play. Compatible: GBC, GBA, GBA SP.
