Wow, this is the first 5/5 in everything I've given this jam, somehow it just managed to hit everything for me. The art and dialogue are really cute and funny (New Yorker Cirno, Sanae's cruel hunger, Yuugi's power, etc.) and the gameplay just clicks really well as a... hmm, can I coin the term Fetchroidvania? The upbeat mix of Maiden's Capriccio really sets the mood too.
The only thing I got stuck on was realizing that one grass was not grass, but in fact Wriggle's hat. But I was rewarded with a Pikmin reference, so all is well.
