| Bug class | Severity | Examples of such a bug |
| 0 | Harmless | Misspellings, small typos, and not-so-easily noticed misalignments |
| 1 | Very minor | Poorly worded sentences, somewhat inaccurate information in text, colors slightly off, great misalignments, inconsistent styles |
| 2 | Minor | Text overlapping, a rarely used feature doesn't always work properly, easily-noticed inconsistent styles |
| 3 | Moderately minor | Distorted sounds and graphics, character action different from intended, a commonly used features not always working properly, text doesn't display properly |
| 4 | Moderate | Sounds and graphics don't play or appear, falling through the land in tough-to-reach areas, faulty collsion detection |
| 5 | Moderately severe | Falling through the land in many common areas, crashes with nonstandard but allowed settings, "file not found" errors upon loading |
| 6 | Severe | Crashes caused with usage of common features, rarely occurring infinite loops, save files frequently not saving properly, blank/not updating screen |
| 7 | Very severe | Crashes where pressing the reset button on the case is the only way to recover, game refuses to run at all, frequently occurring infinite loops |
| 8 | Destructive | Does physical hardware damage, bugs that force you to have to reinstall the operating system (and everything else) in order to recover |
