I like the concept. Seems like a good prototype to an arcadish game.
The main things that bugged me were the controls, the damage/trip recovery time, and the difficulty to actually hit an enemy.
The controls, I would've preferred a mouse for at least the attack instead of enter, or maybe the option of either.
The recovery I felt was just a little too long. It felt like throwing a weight into a high speed mechanic.
The last one might just be a personal issue or it could be a combination of the previous issues, it just seemed difficult to actually hit something without the jump attack.
I like the audio and the fluidity of the mechanics, however! The design overall is an interesting concept
