As much as I loved it, I can't recommend it. The game is so idle-y that it's more like "open us up once a day, spam upgrades, save and close" type of game. I say that because offline progression is broken and gives much more money (at least, in early game) than leaving it open. I though the core of this game is that you're supposed to watch the plinko action, but the best way to progress is to.. not do that. The upgrades scale too slowly, making progression a crawl.
And that's to say that your save might not get randomly corrupted or got broken by the offline progression. If this happens, just prestige. You may or may not lose out on stuff by doing this.
I'll edit this review if anything changes mid-game or late-game. For now, I'll keep pushing.
ps. play Pachinkremental or Rarity Orbs XL if you're in dire need of plinko action.
