4x5 works fine, you'll see ^-^ It takes a little to get used to tablets though, so don't let that discourage you! (just make sure you don't make the same mistake I did and rather look at the screen than at the tablet while you draw - it makes it muuuch easier ^-^ ). $76 is not too bad - usually those tablets cost about $100, so you're already saving $24 ^^ Plus it's good for years, I know I already have mine for a long time, and I doubt it'll stop working anytime soon - Wacom tablets are very robust ^^
Aww, level 2? *patpats* What was that hard in this level? ^^
