Hi,
I found the graphics of the game and the animation of the character really nice! I had some difficulties with the jump button on the 'w', but I guess that is me. I just was not able to understand how to continue the game after falling into the pit. I arrive in a kind of boat and then the game restarts automatically. Also, the enemy projectiles were difficult to spot. I suggest not starting in a position where you can be hit by an enemy.
Anyway, good luck with the Jam ratings :)
