A new (quicker) version of this lives here: https://uglifruit.itch.io/physiced-speed-tweak

Dear uglifruit, may I please re-share your games (not just this one:) on my github project page?  More details about the project in my profile --> https://retrobrews.itch.io/. Thank you in advance! Retro Fan

Of course you may share them!

Hi Uglifruit, thank you very much!

Dear Uglyfruit, what type of licence may I use for this game/your games?  Thanks. Retro Fan

I'm perfectly happy for you to use this/my work however.  Technically it'd be a "Attribution CC BY"  - Copying, changing, distributing are all freely allowed as long I'm credited somewhere. (Andy Jenkinson/Uglifruit).

Looking at the CC website - their wording is "This license lets others distribute, remix, adapt, and build upon your work, even commercially, as long as they credit you for the original creation. This is the most accommodating of licenses offered. Recommended for maximum dissemination and use of licensed materials."

Hope that helps, and if you need anything else /  source code / notes then please let me know.

Also, I've posted a quicker (slightly better) version of this here: https://uglifruit.itch.io/physiced-speed-tweak

Pro tip:  For infinite lives - Break into program, and remove line 850. ;)
