I had a really great time with this! A very well made, beautiful game with some fun puzzles to solve! One of the best GB Studio games I've ever played! Well done!
I did find one bug that you might want to fix: in the time it takes for each funny dog to disappear, it's possible to press A and get another Funny Dog picture appear. I found that if I mash the A button in front of the first dog in the game I can quickly get to the end screen without doing anything.
