Ok, I played through the VN and had fun! The game was very cute and sweat, and the artwork was also cute.
The main issues I have with the game are all technical ones, most of them minor. The critical issue is that, as ShippoK found out, it's impossible to get ending 3 (I looked at the script to double check, more on that later). There were a few other technical quirks you may want to fix though.
I noticed that:
* The scene changes are a bit inconsistent: in some cases you use dissolve or fade when going to a new background or CG, in other cases you don't use a transition at all.
* Also, the first time they go to the forest, the shop background fades out during the transition but Odette's sprite remains until the new BG shows up, and then it disappears instantly, which looks kind of odd.
* Shortly after this, when Odette sees the pixie, the textbox vanishes for a moment, like it does when a sprite is appearing or disappearing, but nothing happens. When I looked at the script to figure out if ending 03 was possible, I decided to check here and see what is happening, and it looks like the Odette sprite is supposed to still be visible after going to the forest, and she's supposed to run off during this scene.
Looking at the code, I'm not even sure why the Odette sprite behaves the way it does during the first shop-to-forest transition, and disappears at all. I guess it has something to do with the way this function works.
But I've never used that before and I don't know how it works.
* When Sybelle shows up in the shop near the end of the game, she has some extra dialogue if you saw her earlier at the hot springs. When this dialogue is spoken, it causes Sybelle's sprite to instantly vanish and then fade back in.
* Like ShippoK mentioned, some of the choice results seem odd. For example,
being nice to Odette about the bed actually doesn't have a result on the ending, despite effecting the dialogue quite a bit in a way that seems like it should have an effect on the ending.
* And most importantly, i's impossible to get ending 03. In order to get that ending, these conditions need to be fulfilled.
1) Mira has to tell Sybelle about what happened so the ending scenes where Sybelle is present occur.
2) The "earlysybelle" flag must be true. This is achieved by seeing Sybelle at the hot springs.
3) The "opoints" flag must be false. This flag is set to true if you pursue Odette in the forest rather than trying to catch a pixie.
Since you never get the option to go to the hot springs unless you first pursue Odette, this means it's impossible to get the earlysybelle flag without also getting the opoints flag. Thus, there is no way to get the Bathing Buddies ending.
Despite the list of issues above, I liked the VN quite a bit. Most of those are all minor issues, and the only real frustration was trying to get ending 03. I definitely look forward to seeing the release with music and the fixed ending.
