I've played plenty of games similar to this one but this feels incredibly uninspired. There's no real incentive to boot it up for more than 15 minutes every few hours. The idle drop rates and increases are so ridiculously low it could take multiple days to make a single unit viable for a stage. Equipment rarely drops and experience gets eaten up faster than a bowl of peas around hungry ducks. Content is locked behind progress, so you just boot up the game, upgrade, and wait until you can win.
