Please check it out if you have a minute. It doesn’t work yet on mobile devices, but I think/hope it should work on all, current, major browsers. Graphically it’s (ahem) basic, you might even say retro (if you were generous).
I’d love any feedback you may have: functionality, code quality/readability, general impressions.
Edit: I am working on learning how to write modular code, and using webpack + babel for building it. The source files are in the /src folder (original, I know), and I hope that the code itself is self-explanatory. Again, please share any feedback you may have.
