Wonderful art and very unusual thing for gamejams - voicover! Abilities are well explained in popup windows, no need for trial and error. Story is not really unique, but there is moral dilemma, you can choose to kill friendly robots or to stop playing.
In this game I found only one flaw - it's pretty linear, and though powerups open new paths, there is no "explore every nook and cranny" aspect of metroidvania.
Great entry and good luck!
