TapTap Universe is a mobile gacha idle RPG set in the science-fantasy world. Playing the game, you can expect the same experiences as usual - just the magic got replaced by magical technology.
This change is the most distinctive aspect of 2d graphics here. Your heroes - the bread and butter of gacha RPGs - will mostly use some modern gears - guns, vehicles, even tablets or drones. Split into several fractions, you'll be able to obtain a whole range of characters - western-ish cowboy, military rabbit girl, super-modern shiny fighters, or singing punks. This kind of approach to sci-fi, where there's still a place for traditional methods, points at some Overwatch inspirations.
At the same time, both heroes, environments, and all the rest are crafted with all quality standards. Heroes are smoothly animated, nicely voiced, and some even come with additional enlivened quality art. The skills they're casting in fights are impressive, easily covering half of the screen with flames, thunder, or other magical powers. Backgrounds are stylish and detailed, sometimes with a parallax effect, and menus are nicely stylized.
The core gameplay is just like in any other idle RPG. You watch your heroes fighting all the time, piling gold & loot whenever you're online or offline. Just click "challenge" to start a fight when you're ready, hopefully getting to a new stage and increasing gains (that can be automated only for VIPs). To keep winning, you'll need to power up your heroes regularly. There's a usual "upgrade" button, mainly using gold and standard resources, and you can evolve your fighters to increase quality. You can also gear them up, upgrade those items, unseal unique "ex-gears," or even provide chip power-ups.
To do all these upgrades, you'll need tonnes of resources - and for this, you can use one of many features from the "Adventure" screen. Aside from standard options like PvP, exploration, or journey (roguelike-like) mode - there's also an idle board. Being there, you can tap to roll a dice, move a few tiles around the board & gather a particular item. Such circling can be sped up - but it'll work automatically even if online - until enough enemies block your way.
TapTap Universe is free and, fortunately, also free from ads. Still, it has PvP, a VIP system (although upgradable even without money), and gacha - while not providing extra draws too generously.
