You did a really good job! I liked playing it i REALLY liked the juice of hitting enemies (when their sprite flashes and particles when they die). i suggest putting a different sound when the player get's hit and maybe add a little camera shake so it makes being hit more noticed and felt.

The game was quite polished for being made in only 3 days, the graphics were a bit minimal but that was fine, the gameplay was good but player & enemies going offscreen should be prevented, the music and sfx was nice, I like all the small animations when enemies are hit and so on, Good job! this was my final score:

The game was fun however there are a couple of issues.

1) no walls: the. character can go out of screen, which results in issues with the game play. As well, the enemies end up following the player ... which makes yet another issue

2)the enemies take damage sometimes on their own..? might be a built in mechanic?

3)score doesn't update at the end. ex i got 1100 the first time, 0 the second time but the score at the end didn't change. unless it represents high score then..?

Overall really fun but the bugs do create conflict in the gaming style..
