Congratulations, you have a concept for a game that isn't Blockland at all.
I read over one part carefully; the weapon part, and I have to say it was 1: Not at all Blockland style. That's FPS style, and 2: Substitute your own weapon qualities? That would result in 1 hit kill 100% accurate ak47's. "BUT I SAID WITHIN MARGIN" and my response to that: now you are taking away Blockland's freedom of creation.
