Boring Tuesdays aren't like boring Fridays. With the latter you're only looking to waste a few hours. As for the former... well, there's still three days to occupy.
Jetpack Brontosaurus can help out, regardless of which boring day it is. JB is about a dinosaur. In space. With a jtepack. That's more than enough material for a game methinks. It's in alpha, so don't get upset if you find it doesn't always co-operate. The controls aren't complex - mouse to look around and the keyboard to move. At the very least, it'll make the next ten minutes or so fly by.
Note you'll need to install a third-party app (Unity 3D) to play.
