Wow, not at all what I was expecting! Quite engaging and great visual direction!
A few things I would like to point out, some of which has already been mentioned:
- The mailbox collision threw me off, since the player's feet aren't anywhere near that of the mailbox.
- I think both the pixel art and the hand drawn stuff looked great on their own but I didn't love them together
- The changing font. It's cool on paper and it does make you think that something isn't right, but it can be a bit much. Instead of removing it though, I'd suggest an accessibility option where the player can disable it.
Can't wait to see what you guys make next!
