Some errors

[DeRobyJ]

I'm running the game on Python2
If it's intended to run on Python3 only, please state it in the readme.

line 1331: list indices must be integers, not float
I used int() around the indices.
This goes for most of the times you use the "mapData" matrix.
You did it too in line 508

line 1385: range() integer end argument expected, got float
"heartNum" is saved as a "ciel" of something: this doesn't make it int, I guess.
So again I used int() to fix

line 190
super().__init__(pos,"bird",vel)
TypeError: super() takes at least 1 argument (0 given)
I'm new to Python, but I think you need to write:
NPC.__init__(self, pos, "bird", vel)

I did a fix to these, if needed I can make a pull request.

The same problem with indices goes for some image loading:
img=images[240+math.floor((self.blocks[i][j].maxintegrity-self.blocks[i][j].integrity)/self.blocks[i][j].maxintegrity*9)]
math.floor doesn't return an int, but a float, so I'm still getting error for these.
