Support for different resolution tilesets
I would like to request that Isleward support different tileset resolutions. Since moddability appears to be one of the core tenets of Isleward, changing the graphics seems like a logical and common request for modders. 8x8 is very limited for graphic expression, although it is in keeping with the traditional terminal-oriented design of roguelikes.
Basic support for differing resolutions would entail configuring the base size of the tiles and putting support for that variable throughout the client. By default, 8x8 pixels is the standard size of a tile taken from the sprite sheets. 16x16 and 32x32 would probably be popular resolutions, as free tiles of those sizes already exist for roguelikes.
Without a complete redesign of the tile engine, we could make just enough changes to support dropping in replacement graphics of a new standard size. Original graphic files would be replaced by new files in the appropriate resolution. For example, sprites.png is 64x544. A replacement drop-in 16x16 graphic would have to be 128x1088.
Eventually we might include support for "themes", so one could completely replace all of the graphics for the game through a mod-style interface, putting all graphics in a subdirectory to override the default files without removing them, so one could change the tileset in whole or part at any time. Advanced theming support might require some sort of indexing and naming convention for individual tiles, so one could replace just the mobs, or just the player avatars, or even add one new tile as part of a separate mod.
