It's a smut game about horses, using deckbuilder mechanics. That is rather precisely my niche, and I don't blame you if it isn't yours.

If that is your niche: the dev has put in quite a bit of work into mechanics and tone, with a unique twist on card restriction to replace the generic energy-per-turn most of the genre uses. The different 'vibes' of partners could perhaps use a bit more clear visual differentiation but have quite notably different play styles. 

You can't really lose this game, but the flavorful end of battle mechanics help retain a psychological stake in 'winning' without crushing you when you end up against a partner your deck can't stand up to. 

Ending could use a simple scoreboard mechanic - just a rundown of stats like win/loss. But overall quite nice.
