One point for originality: there's not many games that take place inside a microwave oven. Shame it reads like any other "my messy bedroom" game. And it's blatant what you've expected to do -- get out of the oven before you get nuked or suffocate -- but the game is still mostly unplayable without the hints because 1) there's guess-the-verb problems, and 2) neither the door nor the shield are implemented as in-game objects that the player can experiment with. Oh, and the author seems to have an odd idea how microwave ovens actually work, so we also have 3) read-the-author's-mind to see how science works in this reality.
Sadly unexplored are the many questions that would help explain how any of this game is supposed to make a particle of sense. Why are you small enough to fit in a microwave? Why are you living in a microwave if it's so deadly? Where'd you find things in your size?
Ah well. It's a small game and there are in-game hints. Play it if you like wacky speed-ifs, but otherwise, you probably want to play something else.
