I really like this game! For the most part, the natural way that everything comes together for each puzzle is really satisfying in the end. I think the only real issues I have with the game are when it doesn't work that way. There's one level in particular early on where you have to get a box to the left of the screen to reach a yellow key. I may have missed the proper solution, but when I played the level I just ended up running towards the left with both boxes available to me and the physics kinda just let it happen. I think it's the lack of a 'proper' solution in my mind that really causes the problem there, which can be frustrating when I don't know if it's right or not as a player.
If there's any other complaints I have, it's that I can't propel myself downwards in mid-air and that the UI looks a little unpolished. It's really minor, I know, and that's because everything else is so well-made! The audiovisuals really compliment the gameplay nicely, especially the visuals (because they directly have to do with it at times). I didn't encounter any real bugs, unlike some other games I've played this jam. It's an interesting take on the 2D platformer genre, as well.
I hope it doesn't seem like the criticism outweighs what I like about this game. Because everything, from the level design to the art and even the music really makes it feel like a proper game that wasn't just made in one week.
