I like the premise of the game, trading memories around to help others who are struggling. The tank controls are a little awkward, and especially for the platforming sections. I like this style of puzzle, I saw something similar once in another game jam, in a game called Boolean Tangram. I did notice that it's possible to "lose" pieces, if you perfectly overlap two of the same shape they just become invisible with no indication of where they are on the board. I had a moment while I was rearranging pieces where I did just that without noticing, and was confused how I suddenly lost two small squares, lol. The art and character design is very cute, and I think the effect of having color only around characters or other sources of memories is a nice touch. I especially like the illustrations in the intro and ending cutscenes.
