v0.11.13

Games that bury their executable are found now. The search went two folders deep, so Dying Light: The Beast — ph_ft\work\bin\x64\DyingLightGame_TheBeast_x64_rwdi.exe, four levels down — reported "no 64-bit game executable found" unless you picked the exe by hand (#43). It now walks four levels, still skipping engine, content and redistributable trees at every level.
