nice first submission. had to play this simple because I saw that your submitted 6 SECONDS before the deadline!! I didn't defeat a single enemy as it was not clear to me how. It felt like nothing I did changed the boss. Maybe bad timing.
Cute graphics, but guys, the controls are very non-standard. I kept pressing the space bar for jump and couldn't figure out why nothing happens. I had to take some time to search up all the controls on the keyboard.
