Just played this game and it is quite charming!
At very first when I ran into the belligerent seagull I was like "wtf is that?!" but I soon realized that the monsters are all in the same general vein of relative whimsy, and I love it. The dialogue between the characters is great and I enjoyed their different personalities. Riya is my favorite.
Combat was interesting, though I felt like there were not that many tactical choices and mostly just used Jump/Dive on Riya and the non MP-consuming magical attacks on the others for most of the fights, but I did put it on the easier difficulty so that might be why. Overall I did enjoy the battles and I am thankful that 1.) you allow a customized number of steps between battles, and 2.) you didn't disable dashing like some people do for no apparent reason.
The mapping is fantastic. I love the atmosphere of the islands and the different shades of blue water. Reminded me very much of some tropical beaches I have visited! I also love the ambience created by all the little fishes and crabs and lizards and other animals milling about in unobtrusive ways (thank god they didn't block movement!), and they were also entertaining to talk to as well! The underwater areas were especially pleasant to look at.
The puzzles were clever and interesting and the difficulty seemed to progress at a very natural pace. Well done there!
Overall I enjoyed this game very much! You three (Indra, Fomar, Reverie) did fantastic work and should be proud!
