(I did pre-release playtesting and slightly extended RPG Maker for this game, but wasn't directly involved in its development.)

Prowler is a kinky action-RPG with really impressive game and narrative design, as well as great art and writing. There are quite a few moving parts to this game between real-time combat, looting, crafting, the large character portrait with visible equipment and reaction to status changes, somewhat malleable story progression and a few more systems that I don't want to spoil here. There is some friction in the UX, but nothing that appears often enough to become a larger issue.

The game released with several bugs, but the devs have been addressing them with amazing endurance and speed so far and appear to have knocked out nearly all of the larger issues.
(The patch notes may contain slight spoilers. I think the flat 5.0/5 star rating after as-of-writing 98 reviews speaks for itself, though.)

The explicit content (generally focused around bondage and/or submission, male-only) is very well-made and the pixel-art CGs are often frame-animated. There's a good amount of variety in themes and situations.

I think what most impressed me is that in addition to the individual qualities of the game, they all come together very seamlessly. Even the more kinky, gamey or a bit funny ones feel like they're a natural part of the world of Prowler alongside its fairly serious story.
