Hello. The game actually supports to be moded, some moders have created some fancy stuff altho they have not published it for some reason.
The version on Itch.io is the official public version of the game, you can join Patreon or SubscribeStar to get the internal versions which are still being tested by users on those communities.
Next version is almost ready and will be published here once I publish yet another version on Patreon, official public versions on Itch ane delayed 2 versions behind of what is being tested on Patreon
