Me and my team deeply apreciate your review, and have taken everything you pointed out to heart. First of all, I'm glad you enjoyed it. All the hard work me and my team have invested has finally shown off.
Now, I will touch upon some of the things you pointed out:
1) Terrain will be improved. Each version I add tweaks and small changes to the overall design to make it fit each individual team. The big problem is with the player bases, which I was short on ideas for how to decorate. However, adding doodads in some spaces would be counter-productive, as players need room to manuever. This will be touched upon.
2) Ai. This one's a bit more tricky to pull off, even harder to actually make it worth the time it would take to implement. But I will strive to add Ai support at some point in the future.
3) File size. This... there's nothing I can do about this unfortunately. All models, textures and icons have been compressed, recompressed, and then ran over by a bulldozer. There is nowhere for the map size to go now but up.
4) Balancing. Alot of time and effort has gone into this to make sure the map holds no favourites, and is easy and fun to play. I can also assure you that the difficulty of Assault mode is intended. Assault mode is not meant to be finished, rather be survived. It has singleplayer capabilities, in that it allows players to play against waves of creeps and play around with the heroes, but Assault's true purpose lies in multiplayer, where the last surviving team wins.
5) Description. This will also be improved over time. The concept of adding youtube videos hadn't crossed my mind, this will definetly be added for future versions.
6) Creeps in Capture the Flag mode. The CTF mode was designed around heroes vs heroes. I have no intention of adding creeps to this game mode. If it draws my overall score down, so be it.
7) More items. Ironically, the next version is to include a new item system, that's much more intuitive, and allows for many, and much more interesting combos. If you check back in about a month or two, you will get to see it in action.
8) The amount of Pillars, I believe, is optimal. After intense testing in 3v3v3 matches, the competitive nature of fighting over the Pillars, while attempting to capture the flag, was most of the time a rush. The income of the Pillars was also, at times, even too much. I was actually thinking of reducing the overall gold gained from them, but you have swayed me to leave them as they are.
That's about it for the parts that need improving. As I said, me and my team have taken this to heart and will strive to make the map as perfect as possible, given our time, talents and willpower.
I thank you once again for the review, and I hope you will check back once the new version will be released. Have a Happy New Year!
