You have some solid game design here. There is a good balance between going fast and not going too fast. The music fit really well to give it a nice vibe. Great work! This was one of those games that I thought - "It's a top down side scrolling spaceship game.. how hard could it be??" But then I died immediately from the tentacles, so I went back and read the tutorial and was excited to try to beat the tentacles the next time through. Great work on engagement!
