Thank you for the message! And yea, the score display is a part that is confusing, and needs to be fixed post-compo.
The rule is that only the BEST score of each creature counts towards the total score. So in the screenshot above, you have three drakes (each worth 180 points = 540), but only one of them counts for the final score.
Instead of showing the total for the photo, I should have showed the total for each creature (and gray out the ones who don’t count). That’s for the next version.
… That said, taking a picture with many on the same monster in the frame should probably give an extra bonus. The scoring rules are something that need to go through some playtesting and balancing.
