I guess the star is pretty clear actually. You don't really need the arrow when you have the star, but it would be useful for people who are easily confused. It's not a major deal, so don't worry about it if it's too hard to implement.
I have an idea on how to simplify the combo list. I noticed that when you got to Party and select a character, it gives you a list of the moves the character has, and if you press "J", it'll give you info. You could just add the key combination to the info. For example:
---PUNCH BLAST---
Gather energy and blast it into the foe.
<Give key combo here>
I've also found a couple more bugs. Mostly having to do with the time of day mechanics. One time, while I was playing in the evening, and I was at Port Ice, most of the screen was dark like it was night, but when I moved, the edge of the screen was orange like it was sunset. Also, it seems like Port Ice turns to night sooner than the levels do. Like it was nighttime at Port Ice, but it was sunset at Banpie Forest.
Also, one time when a boss killed me, the screen moved down, so I could see the space below the tiles, and a second Ize appeared.
And one time, when I chose to "Go Outside" at the base, for some reason rather than going to Port Ice, I ended up at Banpie Forest, and there weren't any enemies.
And one major bug: sometimes If I happen to press the spacebar, the game crashes!
Well I hope this info is helpful. If I find any more grammar errors, I'll tell you about them. Again, keep up the good work.
