You definitely deserve a bonus point for thinking of a great alternative take on the theme of "Run" that is completely legitimate. Coming up with an original idea for a card game is hard, and this has enough familiarity with pattern matching card games it means it's quick to get to grips with and start playing - however it definitely still feels like its own thing.
I actually might be tempted to move away from the low res aesthetic, not just because 2024 is the year of Balatro and as such, the comparisons would be inevitable - but your card designs lend themselves to very clean and precise vector images.
I also think that the card deck could be used for other card games (although they may not be as relevant to the theme of 'Run') so there is definitely a lot of scope for where you go from this starting point.
