Managed to beat the game through the end! I don't know if It's just me that just not quite observant, but I think it would be nice if there's a clear way for the player to know how much they can afford on hurting the dolls unintentionally from throwing them around (accidentally hitting the walls or other obstacles too hard) in an attempt to put them in safety before they're actually "killed". I just think this helps the forgiveness mechanic the game gives.
That's just my slight opinion. It didn't ruin the overall experience of playing this game. I think the game is a fun, physics-based game with fun designed levels and traps! The difficult levels at the end are quite challenging, but completely doable and not frustrating to complete. The retro sound effects are nice too, and works well with the pixel arts. Well done!
