Awww, a shame it's so short, it ended right when I was starting to get the taste of it!
The game is very pretty, I love Akoya's design and the character animations are simply impecabble, I adore how heavy her wand feels, it really shows off itself as a capable weapon. The transformation transition from human to mermaid and vice versa is also a lovely touch, all the spritework here is amazing.
The scenery on the other hand feels a tad bit rushed honestly, it doesn't really look super natural, the props doesn't quite harmonize with the level layouts, and the layouts thenselves also feel very dull, wich is unfortunate, it kinda looks like someone picked an empty video-game level and added a few stickers on top of it instead of being made with the decoration in mind, if that makes sense...
The musics are really really good tho! I really wanted to hear more of them! Again, the game being so short made so that I couldn't appreciate the soundtrack properly!
My favorite is by far the beach theme, it's suuucchhh a vibe!! (In fact, I left it playing on the background while I write this down <3 )
It's also hard to judge the gameplay on such a small time I had to feel it on my own control, but it seens very serviceable, attacks have weight thanks to the amazing spritework and movement felt smooth. I really like that the ranged beams can be redirectioned mid-animation, it feels really great and was an excellent addition at the boss fight.
Alas, I think that's all I have to comment about. This is the start of a really promising entry, but sadly it seens like for now it will stay as promises...
