It's pretty nice looking. The multiboard is detailed and the hero arena maze concept is really cool. The heroes aren't too original (no new heroes with new abilities), but they aren't too boring. Items are nice looking, although not original, they have nicely laid out tooltips. The fact that you have AI is good.
If you released the map, I'm nearly sure it would get approved. However, it would likely get a 3/5. Interesting heroes, great terrain, cool items, and tons of random events might bump it up to a 4/5.
Also, in the INFORMATION menu, Credit is spelled wrong. (You spelled CREADIT.)
