It's pretty clear this game wasn't finished, but I think you should keep working on it and make a post-jam version, even if the deadline has passed.
Overall, in it's current state, enemies cannot damage you, and you cannot damage them. If you hug a wall, you can spam the jump button to rise indefinitely (which even lead to a "How did you find this" message on the right of the map)
For fun, I can't really say there was much to be had, but again, the game isn't finished.
Again with innovation, it's hard to tell just what the end goal was going for. I see you've made another game with the same title, and I imagine it would be similar to it.
For graphics, the background is nice, though considering you didn't draw it yourself, I decided I was going to rate the game based on the design on the characters. I see the main character is reused from an earlier game you made, so in the end I decided not to rate your game for graphics.
Same goes for audio. I feel like you should continue working on this, maybe draw your own assets and compose your own music. I wish I had some actual feedback to provide.
The background sets a really nice mood though.
