I know, I'm not sure if you guys are ever going to get around to update this again, but in case you do, and since some of this engine stuff is used in your other games, you could maybe use the feedback. If some of this stuff has been reported before, sorry.
Bugs/Negative
1) It's not really a bug I guess, but the fighter's fists did this wierd thing I've never noticed them do. Sometimes they "remember" the combo. This doesn't seem to work with breakable objects or enemies, but only on objects that are not walls, you can hit, but won't break. A good example would be the trees that form two lines outside of the bell tower in the first stage. If you punch one twice and stop, then move to another one and punch it, it will do the super-punch as if you had hit three times. I didn't think you could do the combo on anything but enemies to begin with. Just something odd I noticed.
2) Could be my settings, but certain parts of the maps have strange lines on them. A good example is the first teleport room to the Guardian of Ice. The wall opposite the teleport has these black vertical lines running up it, as if the textures aren't lining up properly or something. Hard to explain. If it's any help, my resolution is 12x10 and the rest of the graphic options are set to default.
3) You can easily kill Serpents by ducking. They fire as if you were still standing, so they travel over your head. I'd say leave this to the players to not abuse (I don't!), but I dunno. Maybe this has complications? If the serpent AI isn't smart enough to know to aim down... I dunno much coding, but maybe it could lead to other problems of the game not realizing you're crouching?
4) The Fighter's "Default" stats are far superior to anything you can roll with him. In fact, it seems impossible to roll higher than a 3 in Constitution, yet the "Default" has an 8.
5) When you get to the stat rolling screen, the stats that start there are never the "Default" stats. What I mean is, if you hit the "Default Stats" button, you'll get certain set stats. These are not the first numbers that come up when you get to this screen. I'm not sure if this is intentional, but I'm just pointing out that those are not, in fact, default.
6) In a similar line as 5, it seems that the stats that DO start here are different depending on difficulty. I don't think that's a glitch, but something interesting I noted. Rolling seems to work the same, but I was wondering why there was a link here..?
7) Why in God's name can the Mage roll at 12 in Constitution, when the Fighter can't even roll above a 3, or take 8 as default?! I realize 12 is the Mage's max (and I assume the Fighter can do higher), and he needs that much to gain enough HP to not die instantly, but it seems a little strange.
<!-- s8) --><img src="{SMILIES_PATH}/icon_cool.gif" alt="8)" title="Cool" /><!-- s8) --> Strength is useless for a Mage. There should be some kind of incentive to take it. Even Intelligence and Wisdom are useful for the Fighter.
9) Is the un-powered axe supposed to not have increased range? It didn't seem to be able to hit any farther than the fists.
Positive
1) I like the new stats. More RPG-ish, now.
2) I'm digging the new way to cast spells. Much more convenient.
3) The exp modifier is neat! Add extra challenge, make things easier, or just powerlevel to see what it's like. Great idea!
4) It was probably in older versions but I missed it. Anyway, I love how killing Serpents with the Fighter's flechettes makes them burst into flames! It's very cool!
5) It's still fun!
