I definitely adore the art direction!
The concept is interesting and occasionally it works quite well. It is definitely something I have not seen before, and very loyal to the theme of the jam.
I think the key problem is that it is a bit hard to follow the wave and playing at the same time. I would prefer to see the wave around the character. The wave is also so quick that it does not give much leeway for the player to fail. This is especially prominent at the start of the game where it may take multiple tries for the player to make the first jump and the jump+dash combo.
Controlling the character also feels a bit wonky — almost like there was some lag on all of your inputs aside from jumping and dashing.
But overall, this is a very solid entry. The general idea is innovative and very thematic. The art is among the best I have seen in this jam. Congratulations for the whole team!
