Ahah, I felt so guilty playing as a darn sneaky bloodsucker ! Poor coder, just trying to finish the game jam ^^'
It's a really nice game, and quite funny. I liked the music and the mosquito design. Although I felt it was a bit repetitive, maybe the personne could have had some more pattern or set some traps: hidding under the blanket, add anti-mosquito spray making some areas unreachable, etc... (those are examples clearly based personal experience with those darn things xD ). But they are only suggestions, i know well game jams have a deadline and you accomplished already very much.
Well done and congrats !
