Artstyle and music/audio was fantastic! Personally, and maybe it's my monitor, but I can't really see what I'm doing very well unless I max my lamp's brightness, but then I lose battery before I can attract any mosquitos and lose really quickly. Also I just keep hearing squishing sounds and I'm not exactly sure what those mean. Maybe cuz I can't see very well.

Also, not sure what the ghosts do and what you mean by "control" them. 

I enjoyed the variety of enemies, which made learning the game more engaging as I figured out their unique traits and how to defeat them. Some additional visual feedback when dealing with mosquitoes would be helpful, as it was sometimes unclear if I received the heart boost. The focused flashlight mechanic was satisfying, especially when targeting the blue enemies. A slight adjustment to its movement could improve the experience. Well done!
