I really like the game concept and presentation. It was enjoyable to play.
Unfortunately you missed the mark on one of the primary rules.
- The game must have 90 degree turns in the four cardinal directions, North, East, South, West. Smooth transition between 90 degree angles is allowed. Mouse-look is also allowed. Games which let you turn 90 degrees up and down are allowed.
The way you implemented mouselook works nicely but I am afraid that it's not according to the rule. Your entry is not disqualified and you will still get ratings and comments but you are not eligble for any prizes. It would not be fair to those that follow the rules 100%.
Great job anyways :)
