EDIT: (I looked at the code and changed somethings in a new update.)
>i let the yeti go
That's a bug since for some reason doing certain things made it seem like the mission wasn't beat when it was, it is fixed in the current build.
>Sand tiles are hard to look out
I changed how sand looks like with something pretty quickly made that looks more like sand.
>Everything is named Info
That is mainly to state there is "information to be found", mainly since the event universal variable is called Info. I can edit it without any problems, but it means I need to add a bunch of custom stuff which I will end up doing to the whole game, it will take a while, but it will be done.
