Cool game! It was a bit difficult to understand the navigation mechanics at first attempt, but once I got my head around it I survived the crawl! It would have been nice to have some sort of sound for atmosphere and a more active indication of the frog's whereabouts than the spots, but regardless the art gave an ambience of it's own. I really liked the look of the 'experiment' and the death animation. The colour palette was perfect too. Nice stuff!
