It'd be really nice to be able to just hit enter to restart, rather than having to click on restart. And sometimes, when you hit restart, there's not enough time to move my hand back to the arrow keys to prevent from falling to my death, as The_Corruptor mentioned.
Sure, it says gamegarage.com on the intro. But the if you look at the home page, it also says pastelstories.com, as well as Mateusz Skutnik. Note, there's already a developer named mateuszskutnik http://www.kongregate.com/accounts/MateuszSkutnik who has uploaded mr mothball 2 and 3. Also, if you go to pastelstories.com, there are a bunch of other games that correspond with the developer mateuszskutnik. However, if you go to gamegarage's list of games he's "developed," you won't find any of those on pastelstories.com.
Cool graphics and music, but needs a mute button. As mentioned, drawing is not 100% accurate...but as also mentioned in other comments, the recognition is like...less than 30% accurate (unless drawing a circle). The physics may be a little off, too.
