Nice looking game. I think that there should be a small delay before cerberus shows up, certainly on the first level. I thought the game was bugging out the first time I played because it was a constant half second loop of cerberus appearing and the level restarting.
I think a minimap would be useful to help plan your route as even on normal difficulty it is very unforgiving and often feels like chance.
But these are just issues of polish, which aren't the sort of details that can be expected in a 1 week jam creation.
