Learned bugfixing is not against LD rules, so 1.0.1 update

I've just fixed two bugs that I mentioned in the postmortem.

If any Ludum Dare moderator decides this is against the rules,

1. I'm sorry about it
2. I can revert to earlier commits thanks to Git, and everyone can see them on Github.
3. One can also play the unfixed original version with Godot.

Yet another important thing I learned from this: assertions are not evaluated outside of debug! This is also true for C++ and some other languages.
