Guys relax, this is a classic game development circle :
1-st step realise demo
2-nd small update after 1-2 month after realise
3rd promise about regular update and feedback for patreons
4 start milking
5 after 6-9 month beginning of excuses (problem with PC, low support, problem with health, depressed, had a nightmare and cannot work, etc.)
6. after 12-18 month abaddoned / on hold tag
7. reboot , remaster , remeke current project or new game.
8. repeat circle
No cause for concern, everything is going according to plan.
