I had time to check it, actually it looks playable. But, I've noticed few things :
- Ice. This map is probably going to be a little tatras since you can access to enemy's flag by only taking ice (base ice - mid ice - enemy's base ice).
- A bit campable but, it's a bit risky to camp and a bit risky to try flag. So i wouldn't take this as a bad point.
- The mid is not that easy to line, so I don't agree with you , Abnormal. The mid is open and it's easy to dodge the line.
- Some boxes look weird. They're sometimes cut by a half or so. You might maybe use something different as ramp. Maybe a mettalic thing, but not the same as the floor though.
- And yes, nothing about "space" here.
- Put another way. The mid one isn't enough. Maybe make some way from the two white arrows that are in front of the shields to main maybe.
Otherwise, it looks nice as a first map. Hope this will be continued and be nice.
