you have a maximum per positive/negative element and a shared pool of points (that, btw, do not get allocated automatically once you 'lower' them once)
In fact, one of the things that tripped me is that for the longest time i qualified for the high level abillities and summons, but couldn't use them because of the wrong manual allocation - i was in 'auto-jrpg mode' where usually you don't configure shit at level up (not to mention i didn't notice the negative elements in the first play).
1 small suggestion:
Game is ridiculously easy with 'infinite' scrolls, especially poison, considering you always only use 1 balance point per inventory use, and can even move stuff in combat without any cost at all as long as you are in range...
Get poison and tornado scrolls, win boss fight on turn 1 or 2 with 2 npcs.
Please please, fix the game and remove the 'infinite' part on the stores of the normal game, or (more radical) remove the inventory only uses 1 balance exploit.
Btw: It's easy to miss you don't need to repeat fights if you beat them once, go into the menu where you usual 'end turn', you can run away, which in effect terminates the fight in the same screen and location.
Things i really like in the game are the movement abilities, especially the long range slash and crane abilities - tornado is godly as a scroll, but only 'nice' as a spell - that turn combat into a nice, but not very hard puzzle; as well as a few of the later encounter design; how the shinny pebbles minigame was thought out so the ultimate reward is only slightly above 1/2 of the pebbles in the game, that are hidden quite devilishly (imagine the hell of trying to find them all without a walkthrough), the ability to run away easily on already beaten battles.
The escher-like rooms are nice too.
Things i dislike is how the plot gets quite confused about midway, only straightening up near the end (was that the translator tweaking?), the *ridiculous* backtracking, the moral relativism of some things (Leon is a scumbag) and the weird stuff with that 'inside the body (womb)' sequences, especially the one with the prepubescent girl.
