Cool, thanks! :D
As promised, here's the video of me playing HFK. :)
I played at Insane difficulty level and, after a couple of false starts, I got to level 8. :D
I have to go to work shortly, but I'll talk some more about it later.
EDIT: Back from work! :)
First off, I want to apologize in advance for how flickery and stuttery it looks; I don't know for sure if it's my recording software, or something to do with Java, or just the limitations of my computer, but I tried adjusting every setting I could think of to try to fix it and nothing worked. :| Everything seems to work fine while I'm playing the game, but visual distortions appear in the video, and unfortunately, it seems to get worse the longer you get into the video. :| Hopefully, it isn't too distracting.
Anyway, having keys that are more comfortable for me makes the game a lot more playable and a lot more fun, so thanks again for that. :) I think the video mostly speaks for itself, so I'm not sure how else to comment on it. I hope you find it entertaining/interesting. :)
A couple more suggestions for the game: On the skill upgrade screen, it says "right-click to untrack skill," which makes it show your progress toward getting that upgrade on the main screen. Isn't that backwards? I mean shouldn't it say "right-click to track skill" for tracking your progress and "right-click to untrack skill" for disabling it? And while I'm on the subject, it would be nice if, when the progress bar is full, you could click on it to upgrade that skill instead of going to the upgrade screen. Another thing that would be nice is if the progress bar became a little more eye-catching when it's full like maybe it could change colour? (maybe yellow or white?) Or maybe it could play a sound? Something to draw attention to it, since I often forget about it. :P (Another possible option is to be able to set it so you automatically get the chosen upgrade when you reach that experience level, but I don't know how popular that idea would be)
Just some suggestions to get discussion going; they're all pretty minor things; like I've said before, it's a pretty solid game, so I don't have any major criticisms. :)
