Fun little game, but i have some feedback:

1. Yes, the characters are joined together, but it would be the exact same game with just one character.

2. It´s a bit too difficult.

3. The music doesn´t sound BAD, but it gets annoying really soon. Maybe try a different synth next time.

Hope the feedback helped you, would be nice if you could check out my game "Square Pair" too. :)

Tough game. Agree with another poster than if there were a way to adjust the layouts of the cores, it would make for more interesting gameplay that ties well into the theme. Maybe being able to expand or shrink them, rotate the group, etc.

You control multiple things, but there's not really any way that this impacts the gameplay - you're essentially controlling one big thing as having an enemy in the middle normally results in a quick death, and you can't change the relative positions of your "cores" in any way.

Tough game! I think I got up to six incoming viruses. Would have been cool to track a high score, or time survived. I enjoyed it though, good job!
