Hi, nice to hear that you liked it!
I just watched the video, it was very entertaining with the voices, plus the last time I completed the game was a couple years ago so it was nice to see the whole game again.
The character size was because the original game had a fixed resolution, and now the Unity version runs at a much higher resolution, so sadly there's lots of empty space. And yes, I see that having the character names would help a lot.
I'm planning to do a sequel to this game, and will probably be much better now that I'm a more experienced developer :)
