my game keeps on crashing on one little part and i'm tired of having to get kinda far in the game

You aren't, saving is disabled throughout the game, probably as it's pretty short. The game itself is like 5 minutes long if you follow Temmie's guide for taking the fastest route (from the Extras folder).

What part is the game crashing on for you? If it's on the TV scene, have you tried trying this possible fix or running the unofficial browser "port" of the game?
