what i did to increase the scale of the game is the following:
open index.html, find the `canvas` CSS rule near the top (it should be right there on your screen already), change `image-rendering` to `pixelated` and add either of the following two lines:
```
transform: scale(2.0) translate(25%,25%);
transform: translate(50%,50%) scale(2.0);
```
the first is what i ended up with initially when doing this quick and without thought but i like the second better for reasons.
this has the added benefit of not affecting the amount of mouse movement needed -- if you come at the canvas from the bottom or right side, your cursor will seem to disappear, but keep moving it and it will find the part of the canvas where the game is!
