This is an extremely orthodox idle game. You played things like it. Replace particles going down with an upper limit of stone you have to gather and we get another clone of antimatter dimensions.
Still, despite theme not being realized, this is a well made game (especially given the time frame), with decent balance between wait and action. Manual stone generation is irrelevant after few initial clicks, and the 0th Serenity milestone is missing the word "stone", but I haven't yet found anything flat out wrong about this game.
Well done.
PS: waiting on progress to get the Length rating in. (why is that even a thing?)
