It looks like it has a lot of potential but, honestly, I'm left rather confused after playing.
I'm not sure what any of the different colour planets do or what I'm supposed to do with them, apart from the red one absolutely deafening me. There's a counter that counts to zero but it doesn't do anything when it gets there. I seem to randomly recover propellant so I'm not aiming for more of that... so what exactly is the aim?
I really think if you'd given a little description or inf,o even in just the write up, people would have a better chance of enjoying this one as you clearly have artistic skills and are able to create an interesting movement mechanic.
