Hello, thank you for letting me know. I've tried the game and it's entertaining, but when using this from my laptop and without a mouse, it's quite difficult, but it looks like it's fun to play it with a mouse :)
Yes, I leave the extended versions only on my patreon.
I created the patreon as a way for anyone who wants to support my content to do so, in return I leave some exclusive content for them.
I'm not sure it's the best strategy in the world hahaha but well. Maybe I'll rethink it at some point, I think it would be better for me to leave the extended loops in itch by putting a higher price on them, although money is not really my priority right now.
Answering your question, yes of course, you can join as a pro member and unsubscribe. I think you will be charged the monthly payment. The Eula that I add to this content is that you have permission to use it if you have downloaded the pack as a member. You can download that pdf from there as well.
