I found this out with another bro, trying to see how difficult 207 was, but the thing is that if you walk directly to the left of your starting point, in the middle of the screen, and keep walking... you go out of the map. Its not too serious but, worth a looking into.
That's not a bug. It something players call "glitch"...you can do many more in other maps...also in lv207 they're like 5 glitches that can be done...(walking through, over or behind walls...)
Glitching is against the rules.
1. No hacking/hack leeching.
2. No account sharing/trading/selling.
3. No scamming.
4. No glitching.
5. No staff impersonation.
6. No flaming or harassing of another player of any sort.
7. No using proxies.
8. No multi-clienting.
This is not a bug that can be fixed ever, so I will put it in the solved category since we cannot edit the maps.
Thanks for the report though.
