It's a semi-idle clicker game, ala Cookie Clicker, but a bit more interactive and very cool. There is a definitive end to it which is nice for this type of game.
Looks like someone else already got to this before I did, but +1 to trying it out.
I sometimes think back to this game. I like that the theme it is going for is not always consistently the same. I don't think any other idle clicker has actually given me things to think about like this one did.
Oh yes. I've played quite a few idler-like games, and I hate ones that just go on forever, or for an excessively long time. A good idler, to me, has more mechanics than just spam clicking and incrementing numbers (even though it should incorporate these as core mechanics) and has something that sets it apart from the others, whether that be novel mechanics or some sort of story.
