This is quite a nice homage to the Windows 95 maze screensaver! However, there's a few things I'd like to mention, mostly related to the rat. It took me a bit to figure out how the rat works - maybe it'd be good to make it more clear exactly how it works and how you're supposed to avoid it. The rat also gets stuck in various positions because of its hitbox, and I've noticed that in some places it's possible to take advantage of that, but in other places it's also possible for the rat to get stuck somewhere you need to go and you can't get past it. I'm not sure how to feel about the graphics - it's cool that you made such an accurate homage, but it's also likely that a lot of people will underestimate the quality of this game because of the way the graphics look. Decently solid overall.
