I’m afraid that this game is not going to run on such old OS. Binaries here are 64-bit, but even if I exported a 32-bit one (which you can do yourself from source), it most likely won’t run, as Godot 4 requires newer version of system libraries that Jessie does not have. 32-bit system could also indicate that you are running older hardware. This game is in 3D and not well optimized, so even if it ran, it would probably be single-digit fps. Sorry!
