Is Undertale worth playing? I'm not sure

[Legend]

dunno.  bought but not played.  I've heard it's amazing.  

kind of spoiler:

Spoiler for Hidden:

I also heard you have to get past the first ending to really get it.  having not played it I don't really even know what I'm talking about but the ending isn't the ending. ..and the second ending is also not the ending.  and that's apparently when it gets really good.

I guess I'll play more before giving up on it.
