I love mysteries in general, so this was great. Love the Danganronpa-styled portraits in the 3D world as well as the setting. I think the deduction sequence is great and I like the ending a lot. It's a fun mystery title with some very nice music.
There's a few graphical glitches: in certain rooms like the Chemistry Room, the texture is really bright. Window lights flicker on and off. I got some minor headaches from the lighting. The text is also too small for me.
Also, I noticed that the game seems hard-coded for Left Mouse Button to advance. I use Right Mouse Button for my LMB, so it was awkward for me to use that. In general, I would've liked to use some options.
I also don't mind the exploration, but sometimes I feel like I'm wandering at random to see what the next flag is to trigger.
But really, it's a great game. Definitely impressed.
