I picked this game up on Steam for 2.99. It reminds me of the flash games from yesteryear.
Simple and addictive. There's a little guy in a flight suit and you type any combo of letters and numbers to create a unique environment. You gain points on each run by flying close to walls and through tunnels. Giant polygons, zero realism and only four directional controls using the arrow keys.
