I agree with you about the change to the skin stretching mechanic, I debated about changing it but I didn't feel like it was needed at the time and I needed to deal with the graphics aspect of the game.
I didn't consider much the placement of the key but, yeah, F would have been a good replacement. I'm used to the shift key and that's why I used it. Fun fact, the baby sprites were made as placeholder art using a mouse and photoshop, so that should give you an idea why I didn't add animations; they weren't on my list of stuff to add in the game, tight controls and decent level design were my main goal.
The morbid theme was intentional as the whole conjoined twin skin stretching is too, the sfx were also hastily made and I wanted to change them, but didn't have the time. The needles were also drawn in the same way the babies were.
Thanks so much for taking the time to play and review MY game! In retrospect the game is wayy more difficult than I intended it to be, I'll publish a walkthrough later if you're still interested :D
