Nice game. Like the visuals (especially that slime balls jupming around) and the theme was met.
Anyhow, no music is a letdown. Also the controls could need a little tweaking. Turning gets really fast when holding down the arrow key too long. Getting away from a planet doesn't always work and you ahve to try more times.
And please add a tutorial. I was stuck because I didn't know how to get the violet and yellow slimes, but I found it out over time.
Anyhow, i was not able to finish the game because I could only get 2 black slimes from a random asteroid...
I would really appreciate it if you rate my game too ;)
