Very polished and fun to play! Very unique setting and amazing match for the jam's theme!
To be honest, at first I got frustrated by the difficulty (died like 20 times during "jumping over rift" tutorial) until I realized that I need to spin continuously and really fast. But later the game opened to me and was fun! I'd suggest letting players experience basic movement mechanic first, and only then introduce the more advanced technique of jumping.
Your team did a great job overall!
