Thanks for playing! Yeah, it definitely needs audio, and to be clearer about whats going on at the beginning. 

Good job! Some tutorialisation at least would be good, perhaps with some premade puzzle style layouts? Thanks for the suggestion!

Thanks for playing! I'd like to give it a bit more polish, but i think I'll work on the underlying hexagonal code (zooming, panning etc) before i make any visible improvements.

I aimed for it to be a short, repeatable game, so an enemy spawns every move. I think you're right though, there are too many enemies too quickly, and you don't get yo enjoy the puzzlely part

Nothing really, it's just supposed to look like a planet. I was thinking of having the blue (water) spread more pollution to other water, but it didn't pan out in time

Thanks for playing!
