Please add a support for cpu´s without the SSE4.2 instruction on next update.
SSE4.2 was introduced in 2008. This game was made with the Godot engine from what I can tell, which requires SSE4.2 for 64bit games. You might legitimately need to get a newer PC.
They can't just add that to Godot. If your computer is that old, then you would have run into other issues in the first place.
