No. I mean, no. This shows very little effort. The entire tileset uses maybe eight colors, seven of which are shades of gray. There is no real attempt at shading, and if you look at the example level, you’ll notice that several of the background layers use the exact same colors without even having outlines. The main problem is that there is only one tile for ground. There are also slope tiles, which are a different color, and don’t work with the ground. Most of the tileset is devoted to random eyecandy effects, like painfully flashing pumpkin faces (without even rounded edges), graves, and things I can’t really identify but would qualify as wells in some strange alternate universe. The best parts are probably the gate tiles, which use one color and are somewhat undetailed, but get away with it anyway. Masking is fine.
In essence, this tileset isn’t all that good. It needs more colors, more shading, and I think it would be good if the scale was upped to about 150%. The gates and stuff would look better and scarier if they were bigger than Jazz. (Jazz seems to do quite well in environments that are bigger than him – see Nature’s Ruins for example) It would also be nice if the tileset had more colors than gray. Gray gets really boring really quickly, and in all honesty, isn’t very scary. Take a look at Darkened Landscape for a better example of a Halloween color scheme.
Finally, this tileset is inferior to anything Disguise has ever made. Go figure.
