Love the pixelated style and the sounds!
Also I don't know if this is the intended behavior, but I found it veeeery satisfying to be able to sting the enemies a couple of times, it gives you a higher multiplier, but paralises you a bit, so it's a nice choice to have!
As all the enemies seem to go to the entrance of the hive, I found it easy to just stay there and spam space, killing them all.
Got 24395 as a high score!
Good job overall!
