I had fun with it! I'm sure you know it's repetitive, but you got all the basics down. The control scheme is a little awkward. It's easier to focus on one attack or the other due to the key placement, which works out anyway because each enemy type has a better method of attacking them. I also had trouble with the ambulance because I had to use W to move up and down arrow to go down. Both up and down arrows should work in this case, logically.

Keep at it! Following you to see what's next!
