Actually, they appear to have only been hidden - not ouright removed. By just searching for a game directly it can still be found pretty easily aslong as you remember it's name!

I started developing the game quite a long time ago, but unfortunately, progress has been extremely slow due to the busyness of life. So, I’ve decided to pause everything else for a while and focus fully on development.
My plan is to release a playable first version and try to generate at least enough income to continue working on the game consistently.
Hopefully, it’ll turn into something great in the end.
