I'm using pygame! not sure if anyone else was, but I want to learn python so I've been coding everything in python for a few months now, and its going quite well
works for me, I put the files on a USB stick and managed to run it on my gf's laptop, my laptop and my mom's work laptop all of which I'm nearly certain don't have python or pygame installed...
if it workes it is fine, but pyinstaller only convertes the script in an exe and the module in the video compiles the modules and python + creates an exe. Pyinstaller wont work at all devices but the module will :)
