This is an unexpected entry! I am a big fan of the game Amateur Surgeon, so I am longing for any game like it. Thank you very much for that. The art is very nice, the tools are very familiar if you played Amateur Surgeon, the gameplay is on point. The amount of content is not much, but it's already enough for a one-week jam. Good job!
For a bit of criticism, I'd say it would make more sense if there was a tool that could detect wounds inside the body, and not just by the notes alone. I mean, how is it even possible to know if there is a wound in the first place. I would also suggest changing the cursor to the tool the player selected. It's always a good idea to let the player know they have correctly selected the desired tool. This will ease some confusion especially when using the "hand" tool. Last but not least, it would also be good to add an upward pointing and a downward pointing arrow on both sides of the screen, just to hint to the player that you can look up and down.
Anyway, I think you did a pretty nice job making this game. Keep up the good work!
