Thank you for the great response! So glad you enjoyed playing the game.
1. Yes you're right. That would actually be a great addition to the game.
2. We were debating on whether or not to make the spikes seem different so that the player could logically figure it out. We decided to go with making the fake spikes not able to have blood splat on them. That way the player can end up figuring out which ones are fake. But if they were serious about minimizing the time to complete the game, they would be able to memorize and know which spikes are fake by playing a few times. That way if a player got good at playing they'd essentially have an edge on things like that. That's another reason why we put secrets in the game. If players liked playing enough, they could explore and find optimal ways of getting higher scores. So we're glad you thought it was a little unfair, because that's the path we chose to take. It's always nice creating an environment that you think the player will react one way and then they tell you that they did. That's awesome and your feedback is incredibly valuable.
3. Yes you're right on this one too. Although some levels make use of both directions, it would probably be better to have the camera be a little more responsive so you could get a farther view in both directions depending on user input. Would seriously consider adding this type of feature to a sequel.
Thank you again for playing and leaving a comment! We're extremely happy that you got a kick out of it.
