I've put quite a few hours into this game, probably more than necessary, and I've been waiting to feel out the long game, but it seems like I have to say something at this point.
It's as solid an idle clicker as you can get, fair and decent for what you wait through to get the good stuff in the game, but when you're stuck on the slow parts, you're really stuck. It's like the progression stagnates mid section where it takes literally ages to get near 50B skulls with non-tap and skulls up by 250% power. It's like these power numbers mean almost nothing in the long run. Unless there's some strat that I'm running properly to get the highest numbers possible.
Zeryuu made an excellent point, it's still on 1.00.12 and that could be because Newgrounds can't update any further, but it seems disingenuous of the game to tell me that it's updating when it seems to have stagnated long ago. Hell, I would love to get the Easter update for the items, but there's just nothing to indicate that that will ever happen. Even the update where I could watch an ad to speed up the wait time for the building upgrades never arrived.
Seriously a shame.
