Thank you for playing! The music is from a humble bundle, but I made most of the other sound effects. The blurry background may be because of the smoothing option I have set on by default. I couldn't decide if I wanted the smoothing on or off, so there is an option to turn it off.
I was thinking of adding one more speed option between the two I have now. The flag was supposed to be a subtle indication of where the enemies are headed, but I didn't mention that in the tutorial, I will add this in the next update.
I am still tinkering with the way the bugs work, but I will have them move the same speed in the next update. Not sure if that was what made them look so different.
Glad you had fun and thanks for taking the time to write this.
