When downloading/playing an unofficially distributed mod of this game, be careful and look at [code/charts.js](./code/charts.js) for any bad code before you continue! Any `eval()`, popup, or other malicious code references should be a huge red flag!
Some things to look for:
`eval()`
`window.close()`
`fetch()`
`alert()`
`document.body.style.backgroundColor` (could cause a seizure for those who are photosensitive)
