Cosmic Foreground Radiation

My entry for the Weekly Game Jam 90#, themed "radioactivity". Started a bit late by monday but managed to finish it. WASD/Arrow Keys to move.SPACE to fire Jetpack.MOUSE to look/shoot.Q/E to adjust mouse sensitivity.P to pause. Enemies can only be killed by the same radiation they use. Don't get attached to weapons, be on the move and if you're in a pinch, try entering a portal.
