The initial design is good, but the game is too difficult to support the "one HP" design. With many enemies on the screen, they all just bunch up and you will have a harder time trying to hit the "one" enemy you need to hit.

Hello! Thanks for playing and commenting. You got it right, this game is meant to be difficult and sometimes you have to reload to get a slightly better rng. We've got different opinions on the difficulty, and it's pretty hard to balance it out, maybe some difficulty option work or each death could lead to an easier version of level. Some good ideas always come a bit late :)
