Savegame editing?

I've been experimenting using Waydroid on Linux trying to see where the savegame is and how it looks like.

I've found what looks like a savegame at ~/.local/share/waydroid/data/media/0/Android/data/com.multicastgames.venomSurvive/files/ud_data/VENOM_ud_data.dat

I've fiddled around a bit with a hex editor and it looks like there's a lot of text in there in the form:

<Currency> 0x83 0xA6 amount 0xCA <current value> 0xAF total_collected 0XCA <value>

and so on. If viewing the "<current value>" bit as a 32-bit floating point number with big endian enconding it matches the actual value in the game. I tried modifying the file and that does seem to work on Waydroid i.e. I can set arbitrary values for resources and they are read when the game loads.

Has anyone tried/can anyone try to confirm this? I'm not sure if the "endianess" will be the same for everyone. Also will I require a rooted phone if I wanted to try this process on a device? I mean I can break the game on Waydroid but the performance of running an ARM game on a x86/x64 processor is abysmal when using emulation (at least for me).
