Move around using arrow keys. Arrows subtract 1 hp while bombs does 5. Nuke will -25 hp so it will one shot you. Press h to see your hp When you die you will be asked to press g or b or s. g - means good. b- means bad. s- means spectator mode.
Note: There might be a glitch where you won't lose 5 hp by a bomb or lose 1 by arrow or even lose 25 by nuke. Don't go afk or else it'll be impossible to dodge. Will add baby, easy, hard, and impossible modes. To practice--> https://scratch.mit.edu/projects/519041327/ (has no arrows)
