Hi GaelleOoOo,
Thanks for playing Powers That Be! Most of our games are updated in increments of 0.0.1 or 0.0.2. The current version of PTB as of time of writing is v0.5.6, so it may take some time until v0.6.0 is out. However, our plan is to eventually upload it to Itch some time after it's released on our Patreon as is our usual protocol.
Hope that helps, and thanks again for playing our games! Cheers!
