I also wanted to know if there was a discounted upgrade price to upgrade from the $5 to $20 version without having to pay the original $5 plus the extra $20 for the full version, as i have already bought the $5 version and played it and was thinking of upgrading and re playing with the Vespera Story added.
If you do ever add the upgrade ability, i think there will be lots of other people that would enjoy upgrading without having to spend $5 more than everybody who just bought the $20 version to start with instead of having to buy both versions seperatly for $5 more.
An upgrade patch to add the extra features into the original $5 version might be an option for a certain price like $15 so we can all pay the same price for the same game if we choose to upgrade or buy the full $20 version from the start.
I would love to know your thoughts on if an upgrade patch for each new $20 day update version would be feasable and could be made to work.
