Heroine Dusk, cool in browser retro dungeon crawler

Clint Bellanger, the awesome guy behind the Flare RPG (engine), just landed a surprise hit for the #OneGameaMonth competition(?):

Heroine Dusk

The fully JavaScript (and thus in Browser game) is called Heroine Dusk, and can be played here as a first demo. Game play seems to be heavily influenced by those early 1990ties pseudo 3D dungeon crawlers (similar to the recent indie-game hit "Legend of Grimrock").

Code and art assets are of course fully FOSS!
