Playing this alone is a bit tricky but quite interesting! I liked the simplicity of the idea but the difficulty of execution it brought.
I wonder if you could have some power ups that help with that a bit – like a shield that protects you from a certain amount of hits, magnets that attract blue orbs and reject red ones, etc.
I don't know if there's any in already because I can't get past round 1 sadly. I mean, I did, but as soon as round two started the rest of the blue bar went out!
Nice catchy tune, I liked the two robots (I hope thet get their freedom) and the graphics were quite simple but conveyed everything very well.
Well done!
