Yes, it worked.
Due to being on a laptop though, and having terrible luck, I could not get past the third wave. Not to say that it was for a lack of trying I took it as a personal challenge to not be bested but in the end the game won. I like the premise and its simple nature texture wise. It was a lot of fun and if you wanted to build upon it further it would be of my suggestion to look upon games like Prefect Tower II. The only thing I had a gripe with was that the game didn't give me any chance to build up upgrades and it always felt I was far to underpowered, even in the first level. I understand the intent was to show the game wasn't holding back. I would suggest however that you throw a single higher health enemy at the player, so the player still gets the same sense of threat from the enemies. For example give it enough health to just barely get to the base, or even takes one heart, without the player intervening. Then have the enemy health decrease as you get further till it's to a normal amount and increase the amount of enemies to acording level number. After all the real danger seems to be in the amount of enemies. It is your game so do with my advise as you want, I still had fun in any capacity.
