- Keep the classic rules intact: the first player continues playing until a mistake is made
Yes - this builds tension for when the fail comes.
Yes, we decided to keep this rule within a level.
- Always change turns at the beginning of each new level
Yes - seems like a good compromise. Players of equal skill level will really need to play well to keep the game even.
- Make two rounds for each level, to give each player an opportunity to move first
Might make the game too long?
The game has very short rounds, just a few minutes each. So, we finally decided on the following:
1. If you play against the computer, you always have the first move at the beginning of each level (to make the game more favorable for the human player).
2. If there are two players, each level is played twice, so that each person will have an opportunity to move first. In the ideal situation of two perfectly skilled players, each will win "their" rounds and the total score will be even, but in reality, everyone can make a mistake, especially with difficult levels where it's almost impossible to not lose your own pucks (and your turn) in the middle of the round.
