Magicka is fun, especially for multiplayer, but the combination of the inflexible save system and the bugs have created an unworkable, unfun situation. My friends and I are done playing and are unlikely to buy any DLC or any more games by paradox. I hope someone in a position to do something reads this.
I understand why the save system is the way it is. It adds to the challenge of the game and that's perfectly valid. However, with multiplayer the way it is, where players can't drop in or out and glitches regularly bring all progress to a halt (sometimes in such a way that restarting the game is the only way to get things started again), it's unacceptable to ask players to redo 30-40 minutes of progress because the game is broken.
I just finished a session where three friends and I playing on a LAN got to the dragon boss in Chapter 11. The host's character got stuck such that he couldn't cast any spells, move, or take damage. Eventually the other three players died and the game was left in a state where we couldn't do anything but restart the entire level. We quit in disgust. This was the third such bug. The others included events not triggering, people falling through the level, and outright crashes to desktop through the other levels.
If things aren't going to work, you've got to give players the ability to pick up where they left off! The fact that this hasn't been addressed yet is sad.
Sorry to dump this on the forum. I'm sure it's been said but I figure a larger volume of visible complaints might turn into action.
