Pretty solid physics game. I like that there needs to be intelligence to every movement you do, like you can't just spam swing mode cause there are situations where its a detriment. Smart design right there. I though it would be interesting if maybe, some asteroids had magnetic properties (like for example they get attracted to the red one and cause massive damage to it if hit but at the same time they also get repelled by the blue one and vice versa, so player would also need to factor this into how he chooses to move the bots. Feels like it could work). Most physics games don't really have stories associated with them and I like that this one did. Well done!
