NP!
Yeah, so, synergy should be effects that are more than just the sum of the two things. And relying on your parts for that "synergy" isn't really synergistic, it's just the sum of the parts (literally).
I could have just read the rules wrong; they're not in front of me atm, but I'll work as best I can from memory. I believe you say something to the effect of "moving in any direction the player wants." Particularly in 1pg, you're going to want to elucidate on any mechanic that is contrary to the expectation of the reader. In this case saying "move any direction you want in a straight line" will clear it all up and make collisions more of a thing--though I still don't know if I'd expect them to happen.
To clarify about weapons, I don't think you need "ranged" weapons, just weapons with ranges that aren't 0". That will mean that a player really has to get a biiiig bump to speed to get out of attack range.
