Acid Game Engine

Acid is an open-source project listed on GitHub, but as of now its public presence is minimal (few stars, limited documentation), and there is little publicly available description of its scope or design intentions beyond repository contents. As such it appears to be a small-scale or early-stage engine or toolkit — perhaps experimental — rather than a mature, widely-adopted framework. Because of the lack of detailed docs, it’s hard to say exactly what kinds of games/applications it targets, or what makes it stand out; it could be a personal or niche project still under development. For a developer interested in contributing or experimenting, Acid might offer a playground to explore custom engine design, though the responsibility for fleshing out missing pieces and architecting stability would fall mainly on you.
