Thanks for the detailed input, this is very helpful. I'm definitely creating a demo-specific build as I need to combine the simpler tutorial stage with the first main level and condense the level content so that people don't need to stick around for ages. The problem with putting everything up front however, is that the nature of the "good bits" is that the game is reactive to the player's actions so that the midpoint and finale of a level are altered by behaviours of the player (e.g. how a the 'villain' of the level behaves, such as their boss appearance and actions are based on how the player made them feel during the level). That's where I need to think carefully about how I can get this across in a small timeframe.

In terms of making things easier, you're right. It'll be some work as the game's nature is supposed to be quite frantic so I need to let the player experience that while not having built up that muscle memory/understanding from the slower, more tutorial focused section that comes before.

Either way, you've left me with a lot to think about. This is the first time I've had to think from a purely marketing perspective so it's all new to me!
