MarsSeed [1] filed a deletion request for liquidfun [2]: Orphan package from 2015. Cannot be built: missing a dependency. It is a fork and extension of box2d v2.3.0 from 2013. Project development seems to have halted since 2018. [a] Last release was in 2014. [b] This package wrongly declares it provides box2d. This was intended to be a divergent extension and fork, not one that promises compatibility with box2d. The box2d project, on the other hand, is developed actively. Last stable is from 2020 and is available in repo. Commits are pushed continually, last one is from Feb 2023. Better to delete this broken package without a maintainer and with misleading provides. Nothing on AUR depends on this, only on box2d.
