I've been playing around with monsters.dat all day, and items too!
I abused the system a bit to create some new behavior and features, haha :D
Try it out! There's like 10+ new monsters, and some even help you (but how!?)..
Not gonna spoil anything, good luck completing it though.. I can't even make it to level 6 anymore.
Monster hp really needs min values though, it's too random now, also I increased the damage of a ton of monsters, but usually they barely scratch me and then all of a sudden, bam I die.
(also, 0 or negative atk value crashes the game when the monster attacks)
As for weapons, wands could use a cast speed value, and projectile speed value.
Also here's the Mod, not just a texture pack now :DSeiseki's Enchanted Delver v.0.8!http://www.mediafire.com/?u2m9d5axe9k3417
I have yet to start making tiles or levels, though :>edit:
Also, I so want this on android, but it seems that it's still not loading the textures properly.
