I have a suggestion for a new feature to the gallery:
Maybe an option or a bit of text that becomes available for how to unlock the gallery entry when you beat the level it comes from. It doesn't have to be directly how its unlocked but it could a hint towards it. Or alternatively, something as simple as text document in the files with the unlock parameters would be cool as sometimes it is hard to find the specific scenarios in game or find the circumstances where they begin.
Anyway I really look forward to the next update and level as the game continues to improve with each instalment, either that be bug fixes or added content.
And lastly, thanks for making a really great game.
