I gotta say, for 7 days I was impressed. You nailed the theme from the audio to the visuals I was uncomfortable. I think both obstacles and a timer are great additions to snake. However, the thing snake does best is its difficulty curve. In making a crowded room you have raised the skill floor by a lot, and then adding a timer on top of it raises the skill floor even more. A good way to balance this would be to add a less crowded space in the middle of the map. Players are still going to be forced into the more technically difficult corners because 'there's an orb over there' but it will give the players a bit of reprieve.
all in all a fun little horror take on an age old classic. Well done!
