Interesting
The magnet gains xp as long as something is stuck in the field (even if not caught). I left the game on while I went to give myself a haircut and make breakfast. Came back 20 min later or so, and my mag rad was 340, covering almost the whole screen. That's 2M+ mag xp. IE: just letting it sit makes for an interesting screensaver. Reminds me of Progress Quest.
