This is a really nice, simple game. I like the variation of day/night and just the lighting in general. Also, you came up with a really nice way to keep the player going while keeping it simple. The gameplay is a lot of fun, which is being accentuated by the great graphics, and so is the idea. It also fits the theme really well, so those are all ups. The only problem is, that (as far as i know) there are no sounds/music, and this isn't a requirement of course, and regarding the fact it was only a week and you probably worked alone completely understandable, but of course those aspects can't be rated. But I'm sure the game will do really good in other categories. Nice work! :)
