This is a fun game, nice job! The art is really nice and I especially loved the animation of the rat's tail it has a really lovely natural looking "swishy-ness" to it. The music is great too, I was bopping my head. Like others have said the movement gets a little wonky on the diagonal but its not a big deal to me. Another similar issue is if you attack while moving the attack animation cuts off completely. I really enjoyed the twist that one of the power-ups is just poison and then you die lol I thought that was unexpected and great. Pretty unique take on a common game type, keep it up!
