This isn't an idle game; just an Incremental.
Idle = You benefit (a lot) from time spent waiting, the game just running in the background
Incremental = Lots of unfolding mechanics, setting one activity aside for another as the game progresses
True. But for me its just that it was called semi-idle in the game's description, so I thought this would mean that there would be a good amount of time spent waiting or tabbed out, and while this is sort of true, the way the game played out for me definitely flipped my original expectations. That's fair to point out though, I only noticed the incremental label after I had written out the final paragraph, and at that point I was like eh, works well enough.
I definitely would agree that this isn't an idle game tho, the sort of merge of idle waiting mechanics and all this crazy incremental stuff was what ended up being so cool about the game.
