Ah glad you completed it! :) And normal mode, certainly for the last boss, is still heavy!(..as I'm sure you know!). Hard will be very tricky for the last boss, I haven't quite done it but got close enough to know it's possible, but don't feel bad if it's too tough!.. and for Elton you'd need a pretty good run too (you can only take 10 hits as opposed to 20, so have to be very patient). As for Brutal mode, I kind of put that in because I know that for each boss it is theoretically possible. I have completed the first boss on Brutal, second I am sure is possible as I came so close, but not quite, last as I say on the menu I think is possible but would take such mastery of timings that not sure anybody will get that far! Might try it again when I'm feeling able!
Thanks for playing!
