Finally got to play it (yay!) and I already have some things to talk about.
First, what'd be nice is if you could clasify transitions. I think an easy one would be this: Separate transtions as Battle Transitions, Map Transitions, Title Transitions, Game Over Transitions, Open Menu Transitions, Continue Transitions, and called transitions (using a script call to make it so the next transition is replaced with a selected transition, useful for boss battles).
The transitions are good, but I think people might only see a game as flashy if the screen explodes just from transfering maps. Plus, using a transition to open the just the menu looks a bit too flashy, most games just have a momentary lag or a the screen darkens a bit and the menu pops up.
The explodes are great, but in all honesty need a bit of work. An explode should cause the squares to fall down revealing the battle screen, not a black screen and a basic transition.
The other transitions are all pretty good, I'd probably use them if I had more control over when a transition is active or inactive.
