This pack contains the tiles from my game Ascension: Adventure, a simple dungeon crawl based on Heroine Dusk. This pack contains all tiles in the game, which are edits of the tileset from Heroine Dusk.

All of these are twice the resolution of the originals and use a custom 256-color palette (included).

To clarify, these are the improved tiles from 1.2, not the original scaled-and-dithered ones.
