Remnants of the Precursors

[mahesh]

I installed Remnants of the Precursors, when I try to run it in a terminal I use this command :

/usr/bin/flatpak run --branch=stable --arch=x86_64 --command=Remnants.sh com.remnantsoftheprecursors.ROTP

and I get this message:

maxMB:7891 freeMB:4419 allocMb:1974 bits:64
restarting with MB:2630
Only 1974Mb memory allocated by OS. Restarting game with command: java -Xmx2630m -jar Remnants.jar arg1

Any suggestions?
thanks a lot in advance
