Love the story for this one - it's really unique, and helps make this distinct from other platformers.
The music is great, feeling thematically appropriate and working really well alongside the gameplay to add plenty of energy.
I enjoyed that rooms were laid out in a non-linear pattern, rather than just left to right - really added to the feeling of exploration. It was also nice to have alternate routes back through the stage when I missed items I needed, rather than having to go back the way I came.
Wasn't able to progress past the first level - the game froze and left me on a black screen after the stage end screen. Still had a great time here though :)
