Reminds me a lot of Super Smash Brothers...the controls leave something to be desired, I wish they were a little more responsive. I love the fact that you can customize your own character. Oh and the achievements for deathmatch are easy: put it as teams and put all the computers except on your team with the hardest level, and the other computer on the easiest. This should work on the plunger and veteran achievements.
If this really is the developers first game, I am really looking forward to future games. As others have mentioned, it isn't perfect. But it was a lot more fun than I expected it to be. Magic should be easier to use, like maybe hotkeys or something. I would also like to see more expanded element themes, and maybe pluses like burning/poisoning/etc. I also HATED
Every achievement was cake for me except bourgeiose, I just reset my upgrade points for all the speed, the ones to see through fog, hive mind, and royal lineage. A little tip, if any of the swans die just restart, its easiest to get them in the first minute or so.
