Thank you for the lovely comment!
Definitely agree, we intend to do localization eventually, when the game is a lot closer to being done. We’re open to doing that sooner if there is enough interest.
Automatically sorted stamps is a great idea – How would you feel about that being a purchasable upgrade in the shop?
Wow, you outlined pretty much exactly the direction we want to take the game – a good number of these are already in the works. This might just be the motivation we needed to push for the next update :D
