This is a nice pixel game and it reminds me of the Space Impact game you can play in an old Nokia phone model. Anyways, I love the overall atmosphere as well as the music, especially the music (since it makes one feel like somewhere somehow there's a story in this game).
I actually made a silly story of Robots vs Re(purposed)-bots and such but decided it was overkill for this game.
You know what they say: "Keep It Simple, Silly".
Yep, that's true. Looking forward to something story-based in the future though (since the title Robots vs Re(purposed)-bots seem interesting) :)
