I always make my games playable with only a keyboard, because I'm too lazy to use a mouse XD
Occasionally I'll add some mouse input to some stuff, for proceeding the dialogue in this case, though usually not everything. Thanks for pointing it out, I'll remember to add more mouse support next time I'm working on a project!
I also kind of rushed the cutscene art, since I had to catch a flight home on the first day, and wanted to finish all of it before arriving on the second day. I did eventually finish it, but I do agree it could've been a bit more detailed ^^
Thanks for playing, for the kind words, and for the feedback! I'll keep it in mind :D
