For me it lacked a bit of interaction right at the start, but I'm not the biggest fan of visual novels, so that's more a problem of mine. What might be more of a general problem is the password: I couldn't for the life of me figure out how to enter it. I had to look on this site to find the solution. I would have probably never tried to write it in caps Maybe that could be changed? Or at least mention it on the game's website.
The graphics are nice. I love your character designs, they are so good. The frog is just adorable. Fun little game. :)
