Story - I really love this concept! A little play about cute friends helping their cute friends achieve their goals is super adorable. Really nice work.
Mechanics - Kind of strange, but they made sense when they made sense (if that makes sense). I got stuck on the third or fourth level (the one in your fourth screenshot there) and couldn't figure out how to get under the vine. I spent a good 10 minutes rolling the other little guy around before I just kinda gave up. Not sure if there was a secret mechanic I was missing to bypassing the vines, but I couldn't figure it out even after resetting a bunch.
Theme - On point! I love that you can't complete the level without helping your little buddies along! Such a cute idea.
Audio/Visual - Pretty great audio and visual. I would have loved a little bit of music that plays throughout the game to set the tone during the levels. But the drums smashing as I bonk my buddies around made me laugh. Also I love the paper cutout! Some of the text was hidden behind the curtains a few times, and the text looked a little smushed, but overall the effect was great.
Overall - Fun little puzzle game that really reminded me of Braid! The mechanics were a little head-scratching at times, but you know this. I loved how you brought the themes into it and the art style made me feel warm and fuzzy inside. Great job!
