So charming! I had a lot of fun studying the music while playing this - there were some really intriguing compositional ideas on display here. I've never heard a (...xylophone? marimba?) sound so threatening before. Well, except for maybe in Super Mario 64. That, and the combination between instrument samples and chiptunes was really fun!
I loved the art style here too. The character's expressions were fantastic, but there was a strange sense of melancholy to the atmosphere, which I found quite compelling - must be the lack of colors.
The lack of diagonal movement took a bit of getting used to, but honestly I don't think it affects the end result that much. I didn't expect sine wave functions to be so hard to dodge!
Overall, phenomenal work!
