An impressive amount of stuff for a game jam entry (3d, intro sequence, boss battle), however the overall game feel was setting this one back a bit. It could be improved by having some better feedback when hitting enemies, and most likely faster animations for everything. After I figured out that all I had to do was find the exit of each level, it was easy to just dash through to the end. I was impressed by the boss fight, and the "shaking cliffs" read very clearly that they were about to fall.
Here's a playtest!
