Impressive game, challenging puzzles. I think it would be a little more fun if you could find a way to consolidate the controls - if it were mouse only for example (perhaps you could click on something to ignite rather than pressing F could be a possibility). I also had one character fall into the void and appeared under the level - not sure what I did to make that happen, but the pathfinder was going crazy. Good job overall, really great for 48hours
