An interesting approach to an endless runner, it definitely took a good bit for me to come to terms with the inevitability of losing in this game, since there's no way to completely take out any roaches. I had to rewire my brain a bit when playing this game which made for quite the interesting experience. Rather than trying to take out the roaches the objective was instead just to hold them back even just for 1 second longer which makes the gameplay feel more tense actually. Really good stuff!
Out of curiosity, what's your high score for this game?
