Impressive especially for a jam entry :o
The pixel art is really high grade, the music also fits the game to a tee, perfectly captures that feeling compos from the Castlevania series have with a bit of it's own jazzyness added to it.
Gameplay overall feels quite polished but still has some small issues though. Some jumps are really stretching far to the limit of the max jump height and length the character can reach making some quite hard, this is a bit eliviated when you get the double jump but still, the map helps but some aspects of the level design still feel a bit confusing (with some areas i suppose requiring an upgrade i didn't find yet to get to ? but wasn't sure about)
Now with that said this doesn't take away from the positives and sheer quality on display here, the variety of environements and music, and well general amount of content considering the deadline even for a team effort deserves to be noted.
Overall had a real good time with this one even if i didn't get too far
So congrats, and good job to y'all :)
