Or you could download the trial version of Microsoft Expression Design and export them to a more standard tilesize.
Or you could output as vector artwork, then write a vector engine in DBP
Or you could just scale the png's in Paint .NET, Photoshop (or whatever you prefer)
Or you could put all of the tiles on planes, and use their size to scale them
lol just some suggestions. Personally I've taken a completely alternative route and created 3D models, but then again I'm not using DBP; nor am I competing but after seeing the prototype it let my mind wander to create something of a more complete game that wouldn't be amiss on XBLA
