That's indeed a good idea: it's always good to make it feel more 'personal'. And though it'll take some time, it's probably not too big to program in(?!)

Thanks for responding. Yesterday I played the game again, and I think it's fast and fun. I do think though that adding some more sound-feedback is needed. Though that's not 'in your hands' I can imagine having some extra speech and programming them in both won't be that much hours of work (compared to what's been done already) and will make the game quite a lot better. We can dream of more animations, more songs, etc... but I think the most simple improvement is just adding some audio-feedback for some shots/achievements. The shots themselves are already programmed, so adding some audio won't be that much work. I don't know who recorded the call-outs, but if they're still in contact with Heighway, recording some more could be done in an hour/a few hours if you gave them a list?
Well, that said, I think it's a great and fun game to start with for Heighway.
