Nice! I definitely think you are one of the very top players then! :-)
You can copy the content of the .dat files and paste them to https://pastebin.com/ (one paste per file)
About the performance of the game, have you seen the newest version of DUGA? I recently updated it, so it now supports hardware acceleration on Windows versions. It will run with 30 frames per second consistently when in full screen now :-)
If you want to update and keep your statistics and saved files, you can simply replace DUGA.exe and leave everything as be, then you get the performance upgrade without losing anything!
