Good, the Puzzle/levels are well designed, and the  dificulty go increasing organically.
For  the presentation the main problems is it lack cohecion( look to  pokemon Pearl and diamond remake thats what i mean), itself the graphics are and images are welll made, but they don't work toghether simply the small diferneces in color and style distract to much, it's more a question of trial and error i improve  for itself. If you could use a limited color pallete(lospec.com<--here are premade ones, are mostly for pixel art but can be used in other programs like gimp) you can avoid it a little, and when make background elements like the tiles,. go testing the characther over them to see if are cohecive, other trick is use less details in background elemets or inteactive one.
for the counter side animations are  good.

With concept and  use of the limitation, is solid but i lack something that make stand out.

Cute Game, i liked the death animations, puzzle games are hard to design yours was challenging enough, nice music too Good job

reminds me of old good flash games

Very cool game! And a very, very cool concept! The game also makes very good use of the jam limit! Good job!

Same input - two character -puzzle games are always a fun idea to play through. Enough difficulty here for a small game so that it felt challenging enough.
