I have some constructive criticism after watching your video, Booda.
1) You should make the cloud overlay semitransparent. It would get really annoying to have your vision obstructed every other second by a cloud. Also, they look really cut out. Maybe you can blend the edges a little bit?
2) You didn't have any animation for when you walk in the grass, which has become commonplace in the games found around here.
3) You use the regular speaking message background for the sign. It should be different. There are three types of message backgrounds: Talking, Sign, and General. Talking is white with blue outline, a sign is white with a grey border, and general has a sort of purplish outline.
4) The down-facing arrow in the message isn't bobbing up and down indicating there is more message and to press space or whatever button you're using.
5) In the battle system, the hilighted section that you use to select which move looks off-center at some times.
6) There are no battle animations. But of course, like everything, this is a work in progress, right :)
7) Is that flying grass?
