Decent
Well the game looks decent but its way too short
Another thing are the combat. Its kinda cheesy and you feel like you're hiting air.
Dialog boxes are a bit too small and its hard to read.
Talking riku's sprite look a bit awkward, try making diferent ones that fits more with what he's saying.
Another thing you should do is variate your hit anmation since riku is always doing the same move everytime you press z.
I think I got trough everything. Now for the positives points:
-The overall graphics looks pretty good
-The story kinda got me I'll probably take a look to next episodes
-The system looks solid, just a bit more work should make it even better.
Well thats it I guess ^^
Hope I helped =P
