All 8 of your similar games are hits.

No genre covers most of your similar games. The closest is 2D Platformer (2 of 8), so the genre you lead with is still undecided.

Of the 416 indie games that passed 1,000 reviews in 2022, 11.8% were novel genre mixes and 88.2% stuck to an established genre. Published indie market research.

Best case: Rivals of Aether at ≈ 1.3M–2.1M copies, ≈ $10.8M–$29.1M after Steam's cut. A breakout hit, far above a typical game.

The genre you'd be entering

Your set: Your set clusters on 2D Platformer (2 of 8) and Competitive (2 of 8).
The winners: Winners here lead with Fighting + 2D Fighter, priced around $30. The breakout hits carry Fighting + 2D Fighter + Local Multiplayer; a typical game here doesn't.
The era: The games you compared span 2012 to 2022, and none of them shipped in the last two years.

How these numbers were worked out

A hit here: 1,000+ reviews, roughly $150k+ before Steam's cut (a standard indie benchmark).

Copies come from each game's reviews times a sales-per-review rate that falls with release age, from about 31 for the most recent game here to about 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
