:3 I love it, its a great game with awesome writing! Made me cry at one point but I'm pretty sure i got the True Love ending. Now i cant bring myself to play anymore to see the Secret Route Ending, Since I'm somewhat suspicious & weird, I don't want to take away the monsters & Pc insert's happy ending by resetting.
I don't personally want to ever see the True LOVE (No Love) ending and so I was pretty shocked when the Pc insert woke up with a knife during my second play-through. At my core I'm a soul of kindness though i do have other traits that fit me as well.
I only did three play-through runs and one of those was a caused by a load. After loading up and playing the first time which resulted in no ending [I think anyways] I reset, second play-through resulted in a desktop crash (a scripted one) which I had to used a load, and final play-through is where i got the True Love ending.
This more of personal thing for myself so take it with a grain of salt as a con but I wish the Pc insert could ask for permission before kissing Sans.
