This was really cute! Not only did I get a kick out of it, but my seven year old loved it as well.
I love the style of the sprites, and the little town was goofy in a fun way - I especially liked the extra signs hidden around the world that broke the 4th wall.
Suggestions:
- You may want to try constraining the aspect ratio for the game. I noticed that making the window bigger also increased the viewport, and I'm not sure that was on purpose
- You may want to try turning off vertical gravity while climbing ladders, so the player doesn't immediately fall super fast if they let go of "Up"
- There was a part where Debbie(?) was telling us about the roof guys where she would point us in the wrong direction - I don't know if that was intentional, but I thought I'd give you a heads up.
Over-all, super fun! Great work for your first jam! You should definitely continue making fun games!
