*(Revisiting for some more in-depth feedback)
Absolutely genius concept, I'm so blown away by the way you've incorporated the theme for this game. It has everything you want from a game - from a restart option, to clear instructions on how to play & doesn't compromise on the feel of the game. Sure it has some basic art but I think that adds to the charm (reminds me of Blackthornprod)! One of the best ways you've elevated the simplistic art style here is by adding in things in the foreground to give it depth, I really liked that & it made me feel like it's something I could play on a Nintendo system.
This is a fun puzzle game with an innovative concept & I had so much fun playing. I really had to slow down & think about what I was doing to get through the levels, which I really liked. I played by myself for this one but would be interested in how the co-op side of things works. It's definitely one I'll be recommending for people to play.
What I liked the most: The game feel. the subtle screen movements, the dynamic menu, the animations of the characters. I loved it all so so much - a juicy game is a great game.
What could be improved on: An issue I had when playing was if I moved the block in the first level too far over I had to restart the game, so adding a way where the player could get behind it to push would have been nice.
TLDR; An absolute must play! This is a dynamic game which really steps outside of the box with its genius mechanics & concept. If you've wanted to play 'It Takes Two' but haven't had a partner to play with - this is for you.
