A very cool and honestly quite remarkable game. I'm definitely sure it will be one of Mark's Favorite, no doubt about it. I love every single second playing through this game.
I also love how the AI system work on detecting whatever is happening in the photo. I have a few guesses on how you did it, but congrats nonetheless.
There aren't much to complain, however, I do have to tell you a few things.
1/ Ctrl-Z (I think you know this already)
2/ The ideas are great, but this game idea is going be really hard to be publish as a full game on Steam. This boils down to a problem of not having much going for a game.
The gameplay is cool and people are going to sink their time editing. But without a compelling hook, it's going to hard to publish this game.
I really do look forward to see how you solve this design problem.
But if your goal is to make a fun game, the congrats! This game is super fun.
Overall, a really fun game. 9.5/10
