I really wanted to like this game. The story premise of high school for psychics seems fun and interesting. The character sprites are cute and for a one-person production there is a lot of nice CGs. (Yeah the styles clashed occasionally, but nothing seemed grossly out of place.) The story flowed at a good pace with a nice balance of fun scenes and dramatic scenes, and the dialog had some very cute moments. Also, for a game of this length, there are very few noticeable typos/grammar mistakes.
However, I just couldn't get attached to any of these characters. Starting from the prologue, you have a main character that is at the same time sarcastic and submissive, smart and clueless, and diligent and lazy. Her parents are unbelievably callous and two-faced (and by "unbelievably" I mean they fail to serve their purpose as an awkward plot device). I almost stopped playing before the first encounter with Kaius and Ryuu, and only later realized that the whole introduction was just trying to establish beyond a shadow of doubt why this girl would abandon her normal life so quickly. Maybe you were over-compensating here just a little bit.
The boys she's pursuing go beyond just following tropes. They berate the reader with their stereotypes at every possible moment to the point of unpleasantness. You might as well add "..because I'm angsty and mysterious!" to the end of every other line Kaius says. It would probably look about the same. The same goes for Ryuu and "..because I'm energetic and flirty!" The only guy whose dialog seemed almost normal was Lucan, but then his sprite is blushing more often than not.
I was also pretty disappointed by how the main character's telepathy power was pushed aside once she got to the school.
It made no sense for her to be surprised by anything the boys were doing (other than Kaius) because, for example, her telepathic powers would have Ryuu screaming "I like you." so often that there could be no doubt later in the story. It could also have been used to add a lot more foreshadowing by having her notice, for example, that Ryuu purposely stops himself from thinking certain things. The same goes for Lucan where every scene he's chased by girls, there should be a tinge of guilt in his thoughts. The potential of a telepathic main character was very much wasted in this story.
I'm sorry if I sound overly negative with this, because I do think it's wonderful how much you accomplished with this game. I look forward to seeing what other interesting games you make in the future.
