should probably split up good ending runs into 2 groups, any% (where you just complete all 3 minigames as fast as possible) and 100% (doing everything there is to do in the minigame, e.g. in the tycoon minigame entering the code that appears on the computer monitors into the keypad) or alternatively white star/gold star (because 100% gives you a gold star and any% gives you a normal white star)
yes, theres a code that you can enter in tycoon for a gold star, you go backwards in hallways for a gold star, and another code you can enter and watch a tape in experiment 0 for a gold star
Anniversary ending has now been added, since I noticed that its still available in private servers. Ending isn't really complicated so it should be easy enough to beat the ending.
