The game revolves around Mina, a skilled inventor and "Hollower" who travels to Tenebrous Isle to discover why the Spark Generators she invented to power the island have gone out.

The game is in a 3/4 isometric perspective, with Mina able to attack in four directions using her whip, or burrow underground to traverse short distances quickly as well as cross gaps.

Standing in her way is Thorne, a bat who was the former head of Lionel's guard before he and his shock troopers betrayed the Baron and destroyed the generators.

Development on the solo affair, now under the name Gothic, caught the attention of Yacht Club management, who viewed the title as a favourable pairing to the studio's flagship Shovel Knight series.

[4] Will Greenwald of PCMag called the game ambitious in a preview, comparing it to "Castlevania meets Zelda" and describing the presentation as "charming".

[5] Thomas Whitehead of Nintendo Life stated that he was ultimately "left excited" by the game after playing the demo, calling it an "excellent return" for the studio after making numerous spin-offs.
