I'm honestly a bit surprised nobody else ended up with exactly the same game idea as my team, at least from what I've seen. This one is the closest, but still very different. Other than some criticism that's already in the comments, I'd say press space to separate prompt on level 2 would be helpful, thankfully it is in the description, and the game doesn't allow you to progress until you figure it out. Oh, and your screen transitions are awesome.

Really cool! Very clean, I like the game in general, it feels well polished and the puzzles are quite good! :)

Whoa this is a really awesome take on the theme! The music and movement sit RIGHT in that sweet spot where I could play this for a good few hours. Add some lore and some more puzzles or mechanics and I would pay real money for this one

Very cool idea and I loved the levels! Only 2 things kinda annoyed me but otherwise, great job! 
1. When you're small it's sometimes really hard to see the rest of the map

2. It's not obvious where the smaller doll will come out from

Loved the game, I had though about doing a mecha on mecha loop game at one point, loved the babushka doll concept. Only thing I would change is when portals are left under moving blocks, to show them, as I had to restart a level and pray I was not covering the final portal again. Really nice art and sound design.

great game and concept, good level design too!

Very nice game! I especially like the great take on the theme and how this seemingly simple idea could be made into such clever puzzles. Played it to the end! The only piece of feedback I have is the position of where the smaller version splits from can seem random at times. I also encountered a bug where I could walk through the bigger dolls as the small one. But other than that, great game.
