@ghetdangky: Look at the effects - it'll provide immunity to sleep anyway.
@batlex95: It doesn't need to be longer because of what the next one is, and especially the third...
Creepier than the game was the fact that the "continue" button didn't work when I died... Normally a non-functional button would knock a game down a star, but it fit the atmosphere of the game so well that I couldn't; 5/5.
4/5 b/c no way to tell stuff that does/doesn't disappear in light. Innovative concept that I enjoyed, but I have to know what I'm doing in a puzzle game.
4/5 for what 348joey said and I agree with DexterNeptune - entertaining more than fun. Also, no R for reset (particularly given the impossible-sometimes level nature.
@Notforyourears: Also wrong, they have 4: time, two spacial dimensions and a color dimension which (unlike most dimensions) takes on two specific values rather than a continuous and uncountable set of values. Ergo, four dimensions.
One point beyond @gototheblueflag's accurate comment: it seems likely that the war was nuclear, as the doctor comments on her cough, which could very well come from nuclear fallout.
Simple concept, fairly well-executed, although I'd advice better treatment of edge cases - being very close to active purple/blue squares. Other than that and the annoyance at level 56 (which was quickly resolved when I realized the exit was the only square outside of the typical grid), this game was excellent, and therefore sufficiently good, in my opinion, to be worth a 5/5.
Meh, I thought I fixed the damn button.
