Interesting game!
As you asked I'll give feedback on the user experience which is good, it's simple and easy you click and make choices no problem there!
I kind of sped through the game, visual novels aren't my favorite genre but does the timers or choice really matter aside from the last one?
Most of the time I needed to click all the options and i let the timer run out a few times but there is no real consequence?
I'm probably not your target audience and haven't played any visual novels to compare this too but I hoped some of my feedback helped :)
