Use ↑, ↓, ←, → to move and use and to use your items. I took some creative liberties with it because the original game was just enemy spam, there also might be some secrets not in the original game. Some of the collisions can be janky (probably because it was coded in a social studies class) so you can use w, a, s, d for more fine movements. This game also has relatively bad fps, and can sometimes lag. (this will only be a test for one of the custom bosses I am making) And yes, it is possible to beat the boss, and I have done it multiple times.
