It's fun as I play it

It's a bit of a lazy game pretending to be an idle game, and the repetitive quests are annoying... Offline rewards seem to be better than when it's on, but to clear mission stages, you have to leave it idle or constantly tap things, which is surprisingly tiring. The rewards are sweet, but you need a lot of resources, and the upgrade destruction system will drain your money. I've only bought the ad removal so far... but I feel like spending more will just feel hollow. However, I love that I don't see ads for other games after installing it lol. Having to watch 2-minute ads alone was hell.
