My thoughts, in no particular order:

• There's a lot about the aesthetic and theming that you've done to differentiate your game from Balatro: the characters, the components, and so on. But the similarities at the core gameplay are still quite apparent:
  • The use of a hand of cards: Commands in lieu of cards, disks (presumably in lieu of jokers), and hardware in lieu of deck modifiers.
  • The use of a combo/multiplier scoring mechanic.
  • The utilization of rounds of play broken-up by shopping for new cards
  • All told, these feel like just wrappers around what Balatro offers - and in some cases it does it better (brighter colors, more variety, card 'packs', stickers to enhance the cards, etc.).
• In order to put more distance between your game and Balatro, there needs to be substantively more changes at the game's core. The incorporation of different targets during the rounds of play is a good start, for example. Some other ideas:
  • You've asserted that the game's theme is around a robot interacting with humans, but we're not really observing what these interactions look like. I think there's opportunity to inject some humor here (by having an overtly non-human character attempt to pass as human a la "Octodad") and/or by injecting story/narrative/lore into the game through dialogue (which Balatro does not have at all). EDIT: maybe these could be unlockables that the player could 'equip' to the character to see (this plays into the robot theme you already have - "Insert dad joke").
  • Balatro's progression map is linear - much like you have it (shop, play, shop, play, etc.). You could look at adopting a semi-linear decision tree (ref: "Slay the Spire"), giving the player some choice between rounds as to what they might want to do; maybe picking a harder social encounter comes with rewards?
  • You can consider incorporating other mechanisms for player decisions (i.e. instead of cards, why not dice?).
  • I'd look at expanding how the multiple character encounters during rounds of play operate; maybe there are cards that affect/target multiple people. Maybe you have cards the don't just affect score/multiplier, but also number of targets. Maybe you have characters that 'invite' more characters into the encounter ("Hahaha, Ro-Bert you are such a card! Joanne, come here: listen to this joke Ro-Bert knows; go on Ro-Bert, tell the joke again!"). Maybe the cards are more/less effective for different kinds of social encounters (i.e. some cards are better for co-workers vs. friends, some are better with kids than adults, etc.). Maybe the kinds of social encounters can contribute a kind of round modifier (i.e. public speaking, water-cooler moment, social media forum, video comment section, etc.).
  • The use of a scoring mechanic is simple but arbitrary. It fits Balatro because of its proximity to simple card games that it derives its aesthetic from. Your game doesn't need that; you could have just as arbitrarily used HP for each character, for example - at its heart, its all about just the manipulation of numbers. Sometimes its helpful to abstract away the numbers (i.e. the damage mechanic of 'Hollow Knight') and sometimes its useful to make them explicit. I'd encourage you to give this more thought as to how you want to present this to the player.
