I really like those spot the difference games and at first I was a bit confused because the images don't look exactly the same apart from the general differences, but then I thought this actually added a bit of a challenge to it, which was cool.
A bit of feedback though, I was able to basically just spam click everywhere, so having a certain number of wrong attempts would be cool.
Also, sometimes there were things in the right image that were clearly not there in the left one but didn't count as a difference, which was confusing at times (like the fish on the right side of the underwater image for example)
Overall I enjoyed this game a lot though, good job!
