The next version MEWER is online. This adds a main menu, Tutorial, Tips, and (for flash) Input select functions. Try it here: MEWER 0.7.
I'm not certain what this leaves. I have mixed feelings about changing to a non-sequential series of levels... I mean, yes, it's a good idea. But I think it would involve more work than I have time for at the moment. It certainly isn't something necessary for version 1.0. Right now I want to check for anything important missing (like typos in the tutorial explanation, or missing info) before declaring it 1.0 and advertizing it to more people.
