Really enjoyed playing this, great little game. Nice simple visuals which work perfectly with the gameplay and great music. Really appreciated the light humour and storyline and enjoyed the difficulty options with each level, great idea. I'm not sure what the choice of characters really added to the game, if anything I feel it detracted from the story if you're changing characters as you progress through the game. I didn't notice any change in abilities or difficulty with each player so I assume it's purely aesthetic? Overall I really like it and would love to see a sequel or extended version, could happily play this for a much longer period of time. Completed the first play through on Contact in 1hr 40mins and although you have the re-playability in other difficulties the storyline is already over. Already recommended it to a few friends!
