First off, that is a juicy gun, I tried making something like that, but couldn't get it quiet that juicy. Next up, the voice acting... I love it! The little, "meow!" as they get hit and die is adorable. I only made it up to 47 points, though with slightly improved controls, I think it would be easier to get further. I think the issue with the movement is that the tiles are at a 45 degree angle, but you move with regular up-down left-right movement, so changing up to be 45 degrees should fix that issue. Overall, great entry!
