Ugh that's frustrating, I'm sorry. I was hoping graphical things like this would Just Work by using an engine like Godot. There's a "compatibility rendering mode" that I can try that apparently works on lower-end hardware, but it makes the game looks like this.
I can try to bring things under control and get it looking right in this mode, but could you test to see if this build allows the game to run on your device before I go down that rabbit hole? I just uploaded LancerTactics_0_02_05_DEBUGCOMPAT.zip to the itch page -- let me know if you still see the crash when running that mode.
