I run a glibc 2.33 and your game wants at least a glibc 2.34. glibc 2.34 is really recent. Could you relink with an "older glibc" ? --------------- technical details: ABI selection for non-open source program is fully manual on elf/linux. You have to use .symver binutils gas directive (or the quick and dirty way: use an "old" glibc for linking), documentation is here: https://sourceware.org/binutils/docs/ld/VERSION.html You have to select an ABI (external and internal symbols), a glibc around 2017-2019...

Just keycodes will be enough, no need for the key symbol.

... got a cramp... :'(

Have to set monitor to 60hz. Perhaps a patch could help? Also would it be possible to add BGM and Sound FX volume sliders?

Would be nice to quick restart a run or turn the visual filter on/off.
