The sprites, aside form being made from an app aren't too bad, but it also makes it lack certain finer features the characters may have, sometimes the looks do seem not to be matching up. Nothing terribly wrong with a self insert, but the only concern is not to get too involved compared to the other characters. The English right now is a bit off/not proper, but at least clearly still conveys the intention(s). Could use some more descriptions and brief interactions for transitioning from one scene to the next (standard, minor (brief), standard/major(core plot and may be dealing with/leading up to a puzzle) , minor, repeat, for an idea). Discarding the prologue part, you have the class and canteen scene, (the car ride that was skipped, but it is your choice to gloss over it instead of a brief scene, so that its more than "a safe trip").
KLACE! <3 Only know him really by his games though ^^; Oh! And... Your Cute! XP
Once the story really gets underway, jeez..., is this "The Quite Place"???, While I did manage just enough of reaction time to finish the QTE portion, I am only a modest gamer reaction time along with hand/eye/mouse coordination. There may not be many readers who are as used to it. Also one failure is game over to boot too..., but I wonder what game over actually means? Also they were saying to NOT cross a threshold, before suddenly appearing at said threshold border, suddenly switching to YES. Very curious...
