Great game! Really nice visuals and music.
I think using a bit different music as the bugs increase and using different music between the levels could improve the atmosphere giving the player more feeling of tension during the level.
Also I think I found a bug. After the first level I could see a white arrow appear at the beiging of each level before the actual arrows spawned which lead to me losing a life each time i tried to press for it.
I really enjoyed this! Good job and thanks for making it!
