I think the graphic style is pretty cool and adds a great aesthetic feel to the game!
The game is pretty polished and I like the idea of the cameras detecting you, what might be good is to show their line of sight more clearly for the player though! The only other thing is that I felt the player was just a tad too heavy, although this may be intended design because you can change the jump scaling!
Either way, great game, treat yourselves to an 11th cookie! Game on!
