This is awesome! It has a really distinct style reminiscent of flipaclip and old flash animations. As well the sounds and music, definitely suit the cartoonish vibe of the game. The gameplay had me constantly stressing about which bugs were about to bite me, and which one's were more worth my time. Overall an amazing game! I think the only improvements I would suggest is to change the way the nits timer is represented, since them overlapping made it hard sometimes to tell at a glance what timer belonged to which nit (Maybe instead you could have their circles coloured to show how close they are to biting you; green to yellow to red). The only other major issue was that the scaling was a bit off, perhaps due to discrepancies between my display and the display the game was designed on:
However the game was still very playable and I had a blast! Amazing job!
