Whilst you're at it, it's worth considering preordering their upcoming procedurally generated survival sidescroller, A Valley Without Wind. Preordering nets you a 50% discount, and instant access to the current beta build. Impressions from the initial beta release here, although it's had a sizeable amount of updates since then.
