If you want to play this game offline and without any browsers after December 2020, then download .swf game file and use any Flash Player that runs .swf files.
For Windows users, I recommend ARFlashPlayer (it supports fullscreen option) or official Adobe Flash Player. Both programs are portable.
Another way to play flash games is to install SuperNova SWF Extension (it works in Chrome only).
