Cambridge-based Jasper Byrne, who made the move to become a full-time independent developer yesterday, has just released Soul Brother, a clever and stimulating puzzle-platformer now available to play for free in your browser at Adult Swim's site.

Soul Brother features a group of different creatures you can control, each with different abilities useful for progressing through each screen and collecting gems -- flying, double-jumping, pushing blocks, and being tiny. 

Different obstacles require different abilities, and you'll need to kill your current character to possess other creatures. Naturally, Soul Brother is designed around this mechanic, and has dozens of suicide-encouraging puzzles. Go play it now!
