God damn son, did you steal all of agdg's juice?
Really really good, lots of weight and the combat is fairly balance.
At this point i'm starting to think the sprites just gimp your look, maybe you should try making 3D spider eggs and spooders, considering how nice your weapons look, you should do a good job.
Also, you might want to try to add some faint background objects, so it's not pitch black out there and maybe some dithered ambient occlusion, so the cave navigation is not a nightmare, but other than that, extremely well done!
