after a hour and a half of constant clicking i think what could have made this game better is a story to go a long with the game, more random quiets after every level and before every level, instead of a small playing area make a huge area were there is lots of robots and sushi everywhere, and also a inch wide area to the far left of screen were the demon pill, the pause button, the amount left on the wave, and what level your on. These are small suggestions to an already great game.
i don't like it. sure it's fun for a little bit but then it gets boring, and it isn't challenging at all. But it was a fun game for a little bit so 4/5
