I like your game! My list of highlights:
- Soundtrack is really cool!
- SoundFX are equally great - especially the "voice-based" ones, recorded them yourself?
- I love the themes space, dystopia and I am a huge fan of Octopodes - your combo comes very natural to me
- I like the mechanic: You have to accept the danger to destroy the nasty shippies.
Pixel art is not my preferred style, but apart from that, you did really well with executing it.
Suggestions:
I missed the ink blobs completely in my first run (dark on dark). I thought the new octopodes are the "ink" and was trying to steer them into the ships.
One idea how to solve this: When players start flying around, and the first ink blobs are coming up, freeze the game and point with an arrow at one of them, saying something like "ink is destroying ships". Player sees it, can continue and that needs to be learned is learned :-)
What I don't like...
...is that others are much better with playing it - will try to get into the Top 10 later in the evening ;-)
