Fantastic! The whole experience just gels together really well, with the clean 2-bit art style to the choice of music and the environmental design to match the brain setting
Platforming is tight and responsive, and it's fun to try and figure out how to minimise jumping. It'd be nice to have a slight acceleration and deceleration to sideways movement, but besides that the speed and jump felt just right which made for a great experience.
Also, just wanted to say that I loved the look and feel of the chains for suspended platforms and bridges :)
