Enjoyment + Concept 4/5 - Although there's no gameplay, the idea behind the story is really wonderful. I'll discuss it more in a sec, but really nice visual novel type thing. Only thing I can knock it for is that looking is bugged for me as I keep turning right. Otherwise, it does what it needs to for the message.
Presentation 5/5 - Simple and somewhat rough, but perfectly fitting for the game. I love the charm in the UI and old frog plus the lake and the rest of the world being unfinished was such a neat detail to notice.
Use of Limitation 5/5 - Man. I never would have expected this twist on "limited time", but this game called me out hard with the message. I mean it when I say that this game's moral is beautiful and important and the way it's presented is perfect.
Overall, a nice visual novel that has some really touching and important things to say. Nice work!
