i dont know if its just my eyes or my monitor but i had a really hard time with the tiles you walk on being almost black and the tiles that kill you being totally black. also none of the popups explaining what to do stayed on my screen long enough to read them so i had to figure out what i was doing as i went and it was a bit of a struggle. i think there is a good game here but i cant get past the first few levels because i cannot see the difference between tiles i can walk on and tiles that kill me without being really close to my screen.
