That was a cool little action-experience, with some neat theming to it! ^_^
Mechanically, I think that my favourite thing was that one could change the music on the fly--and that it had an effect on the player's capabilities! That felt neat, and nicely-fitted to the musical theme.
The "dash" mechanic was also appreciated, especially once I came to learn to rely more-heavily on it.
And indeed, the "dash" was particularly well-realised, I thought: it was responsive and quick; its trajectory could be altered mid-dash; and it reacted rather well and smoothly to obstacles, slipping the player around them! Well done on that! ^_^
Visually, the art was simple, but effective and cute.
Narratively, the story was surprisingly engaging, given that this was an action-centric jam-game, and I did rather enjoy the humour--and especially the (cat-)puns--therein! ^_^
I did find a few things, if I may, that I feel might have improved the experience for me:
* I could have used more feedback on being hit, I feel; as it was, I found it very easy to miss that I was taking damage.
* I really would have liked a map. (I have a poor sense of direction, and like to explore thoroughly ^^; )
* On my current volume-settings, the music was a bit loud for me. An in-game setting would have been appreciated.
However, I do also realise that this was a jam-game, and that implementing these things may not have been feasible in the allotted time!
And overall, I had fun with this!
Well done to you who made the game! ^_^
