I guess it depends on how you played the game x3 (Thanks for checking it out, btw!) 

Basically, if you ever started a new game or reloaded a different save after getting a bad ending, it will mess up the way the bad ending points are accumulated and they won't count properly during the playthrough. So any time you get any end whether it's a good one or a bad one, as long as you're in any route that isn't the ??? route, you don't want to be reloading saves or restarting anything. You just keep going through all of them because you physically cannot get a game over outside of the ??? route. All bad ends in the other routes will just automatically rewind you to a safe moment for you to pick a different choice, and only then will the bad end point be counted.

There is a bit of a cheat you can do though if you've already seen all of the bad endings listed in the bad endings checklist text document inside the game folder for anyone who didn't realise you need to be playing on just 1 save file :3 I will put the cheat below underneath...

SPOILERS

You can kind of cheat the bad end points system with a bug that I purposely left in just in case anyone got stuck with not getting enough points to unlock the ??? route :3

It can be done with any bad end in the game, but the fastest and easiest way to do it is to play the Student route.

1) On the first choice, make sure not to pick the bad end, pick that you agree with Lana to continue. 

2) On the second choice, the one about having lunch with Seth, pick the one that leads to the two bad ends (say that you will have lunch with Seth.) 

3) Once you have agreed to have lunch with Seth, get to the next choice, you can pick either one since both lead to a bad end. 

4) After you get the bad end and the female voice asks if you still want to have lunch with Seth, keep saying yes. You will end up in a loop of getting thrown between those two bad ends. Don't reload anything. Just keep saying yes to having lunch with Seth and skip through all the text. 

5) If you want to be extra safe, occasionally make a save, as sometimes skipping text can cause Tyranobuilder-made games to crash >.<

 I don't know how many bad end points you're missing, but I think the points requirement to unlock the ??? route is either 28 or 32 (it's been so long I can't remember xD) To be extra safe, you could do this 32 times. 

6) Once you've swapped between those two bad ends 32 times, make a save. Then when the lady asks if you want to have lunch with Seth still, say no this time, and just finish the Student route until you get to the good end. 

That should give you enough points to go straight on to the ??? route :3

Sorry if it's not a very good explanation >.< I suck at explaining stuff :( haha. Also, I can't remember for sure cos it's been years since I made this game, but I think there might be a couple of endings or paths in the ??? route that will only unlock if you have got all of the good endings from the other routes too on the same save file that you're entering the ??? route on, so that's something to also keep in mind x3
