Well-put together game, constantly reminds of Celeste (despite having a unique mechanic that sets it apart) and it has difficulty to match. So far I have made it to the Phrygian stage. The graphics are minimalistic but that doesn't mean they're bad, in fact it's beneficial to be able to see the collision boxes directly, something which Celeste couldn't do. Music is fitting and not repetitive. Solid rating on all counts.
I struggle with consistency especially chained jumps but I think that's more of a me-issue because I have the same problem with similar games. Make sure you have horizontal momentum if you are trying to chain a jump or it will behave as though you mis-timed it.
