Just a quick thing I've noted after playing a few games: When you finish a tactical battle, my mouse cursor stays with the movement cursor (winding dots with an X at the end) during the level-up screen. Because the +/- buttons for stat changes are so small during that level up screen, it makes it very difficult to assign points -- the first time I saw that screen I actually thought the UI had gone non-responsive.

Changing that cursor back to the normal cursor would definitely be useful to allow us to distribute those points. I believe what's happening is that the cursor itself isn't on the X, but that's where it appears to be, at least for me. Changing it back to the feather would make it much easier to see where it is that you're trying to click (or making the + and - boxes about 30% larger).
