uhm, we sold some updates from time to time separately on itch.io, so that people who don't want to use Patreon can get access to the latest update. It was always written clearly in the header:
"FUTURE UPDATES ARE NOT INCLUDED! THIS IS A SUPPORT-THE-DEV-THING :-)"
If you didn't notice that and feel unhappy about that you can write me a PM on Patreon.com/doianu and I can give you a link (this time). However, you are the first one who apparently didn't see the disclaimer :-)
