All those different characters... And still I see no reason why I should pick other than the archer. Killing dragons and Evil Spirits from behind cover. Oh, and I also wanted to say: Walrus on Legs is cool!
Checkpoints aren't necessary. It's just more difficult without a challenge and you're not used to a little challenge. Besides, there are some reasons why there are no checkpoints, I guess: 1. it's more realistic and dramatic making one wrong move and all your effort is for nothing 2. what about the plane's health? If you reach a checkpoint on low health should you have full health on your next try or always the tiny amount?
What would be good was a way to skip a part of the beginning of the level where there is no action and you just fly for half a minute. Doing this over and over makes it a bit boring.
Pause button would definitely be a good thing.
5/5 for me.
It would be nice if you could 'kick' a game host, who is not responding. Often a player starts a game which stays up for an hour without starting, even if the room is full. You should be able to press a button that will end this game if the host doesn't answer a timer of let's say 30 seconds.
Score should not be calculated just on number of people you kill, but on hits or something like that. Because now you can hit all other players five times, but not getting any points if someone else finishes them.
Control is hard, but you can get used to it. But common, defeating 18 enemies, always the same kind of battle, before levelling up once? BOOOOORIIIING! Not enough variation before that first level-up so I quit. 2/5.
I had a kind of bug with Robo Johnson. After a while, he was just running around with an empty railgun, not firing. So there goes my challenging epic boss level...
