Very nice game, let me play it ;-)
I noticed that you did a lot of free games, how do you find the time? Do you only do the coding or also graphics and sounds?

This game could benefit from a tutorial, or a better scaling in difficulty. The first map should most likely just introduce the idea of portals in a safe environment (: I hope to see more games from you in the future!
