Sorry for the double post but needed post some updates.
I am currently working on adding more levels to the game, especially more challenging and puzzling. Some so complex I'm having to make some more to smoothen the difficulty curve out abit. Hoping to get up to 15 rooms, if not 20 for the next release.
I've added Laser Sensors, which despite originally being a hindrance and therefore helpful in killing yourself, still have the ability to do mean things to you, like stopping you from jumping in that spike pit.
Here's a shot of one of the newer levels, still in testing. It's twice as big as the previous levels, being 640x480 rather than, 320x240. I disabled the camera to take this shot, so don't worry about random rooms zooming in and out.
