Heed is a short adventure game created by Ben Chandler (Annie Android, Shifter's Box) using the reliable AGS engine, where you assume control over an unnamed protagonist who is searching for the purpose of his existence. There's not a lot of puzzles in this release, and none of them are particularly difficult, although the game has been structured in such a way that you would only find the interesting ones in the second half of your adventure.
