AngryFireChozo is a ROM hack of Super Metroid by DSC. Unique to this game are unintentionally modified physics quirks, which the levels are designed around. As a result, it is substantially harder than the original game, which isn't helped by the original developer admittedly not doing enough playtesting.
Hoandjzj nevertheless collects every item in the game and reaches 101% as fast as possible, glitching the game out in the process.
